Mxene Sheets(Mxene 床单)研究综述
Mxene Sheets Mxene 床单 - The enhanced catalytic performance was attributed to the excellent property of MXene sheets and the effective interaction between ZnS NPs and MXene sheets. [1] MXene sheets are adsorbed on the surface of a composite foam of MWCNTs and TPU (referred to as TPU/MWCNTs foam), which is prefabricated by using a salt-templating method. [2] MXene sheets, as new 2D nanomaterials, have been used in many advanced applications due to their superior thin-layered architecture, as well as their capability to be employed as novel nanocontainers for advanced applications. [3] The resultant MCF sensors exhibit fast response to compression, and show excellent cycling stability (2500 cycles at 10% compression strain) in the radial direction, which is attributed to the highly intrinsic conductivity of MXene sheets and the oriented structure of cigarette filter. [4] The process involves the insertion/desertion of desolvation-free cations, leading to an abrupt change of the interlayer spacing between MXene sheets. [5] Herein, an environmental energy-enhanced solar steam evaporator is fabricated by immersing a cellulose acetate fiber-based cigarette filter (CF) in an aqueous solution of polyvinyl alcohol (PVA) followed by freeze-drying and decorating with MXene sheets. [6] More importantly, three dimensional (3D) cross-linked graphene or/and MXene based materials, where graphene or/and MXene sheets are interconnected into a macroscopic monolithic bulk material, can achieve excellent electromagnetic interference (EMI) shielding and microwave absorption (MA) performance, together with lightweight, exceptional mechanical properties and so on. [7] The process involves the insertion/desertion of desolvation-free cations, leading to an abrupt change of the interlayer spacing between MXene sheets. [8] The construction of the porous structure can effectively solve the self-stacking problem of MXene sheets. [9] The composite with PTFE would effectively alleviate the oxidation of MXene sheets. [10] Efforts for delamination or exfoliation of MXene sheets are introduced. [11] The as-printed frames are reinforced by immersing in AlCl 3 /HCl solution to remove the electrically insulating AlOOH nanoparticles, as well as cross-link the MXene sheets and fuse the filament interfaces with aluminum ions. [12] Herein, we report large size exfoliated Mo-MXene sheets, which provide a flat flexible interface for decoration with carbon quantum dots (CQDs) and controlled surface phosphorization (denoted as Mo-MX/C/P hybrid). [13] , Ti3AlC2) using hazardous HF or alike, leading to MXene sheets with fluorine termination and poor ambient stability in colloidal dispersions. [14] The composite interwoven by CNT tentacle enhances conductivity and prevents the restacking of Mxene sheets. [15] Herein, durable EMI shielding ramie fabric with flame retardant and self-healing performance were fabricated by depositing ammonium polyphosphate (APP)/polyethyleneimine (PEI) layer, MXene sheets and polycaprolactone (PCL) layer. [16] The enhanced shielding capability is dominated by the electromagnetic absorption owning to high conduction loss in m-MXene network, multiple reflections between m-MXene sheets, and polarization effect on the surface of m-MXene sheets. [17] The tight contact and adequate adsorption of the MXene sheets with the cellulose fibers endow the electrode with uniform conductivity and high stability over a large area. [18] The transformation of MXene sheets into TiOF2 2D sheets with superior electrochemical performance was developed. [19] This breakthrough resulted from the realization that the edges of MXene sheets were positively charged. [20] The Silicon/MXene composite papers are synthesized via covalently anchoring silicon nanospheres on the highly conductive networks based on MXene sheets by vacuum filtration. [21] The electrostatic repulsion forces originated from the negative charges of MXene and NR latex enable the MXene sheets to selectively distribute at the interfaces of the NR particles, forming an interconnected network for efficient electron transport and load transfer at low MXene contents. [22] Nafion, as a surfactant, results in an ordered layer-by-layer deposition of MXene sheets by filtration. [23] Due to the electrostatic attraction effect, positively charged poly(diallyldimethylammonium chloride) (PDDA) long chains would attach to negatively charged MXene, which prevented the newly peeled-off MXene sheets from agglomerating and reduced the collision from the steel balls. [24] Here we review the electrical measurements of bulk assemblies of MXene sheets and demonstrate that the results strongly depend not only on the MXene’s chemical composition and structure but also on the form of assembly (a filtered, spin-casted, or sprayed film, a pressed disc, a particle, etc. [25] The energy/power density of the MoSe2 SSC device is comparable or even higher with the reported SSCs using 2D materials such as graphene sheets, siloxene sheets, and MXene sheets, respectively. [26] Furthermore, MXene sheets with high conductivity can enhance the responsiveness to the terahertz wave. [27] Reactive force fields can accurately describe chemistry of the MXene systems to provide insights to the ion intercalation and water diffusion in MXene sheets as well as measuring the friction coefficient of these structures. [28] Furthermore, as verified by theoretical calculations and experimental investigations, such "potassium-philic" MXene sheets can induce the nucleation of potassium, and guide potassium to uniformly distribute in the scaffold upon cycling. [29] To harvest the solar energy for photocatalysis, we fabricated a nanohybrid system composed of bismuth ferrite nanoparticles with two-dimensional (2D) MXene sheets, namely, the BiFeO3 (BFO)/Ti3C2 (MXene) nanohybrid, for enhanced photocatalytic activity. [30]增强的催化性能归因于 MXene 片材的优异性能以及 ZnS NPs 和 MXene 片材之间的有效相互作用。 [1] MXene 片材吸附在 MWCNTs 和 TPU 的复合泡沫（简称 TPU/MWCNTs 泡沫）的表面，该泡沫是使用盐模板法预制的。 [2] MXene 片材作为新型二维纳米材料，由于其卓越的薄层结构以及可用作高级应用的新型纳米容器的能力，已被用于许多高级应用中。 [3] 所得的 MCF 传感器对压缩表现出快速响应，并在径向显示出优异的循环稳定性（10% 压缩应变下 2500 次循环），这归因于 MXene 片材的高固有导电性和香烟过滤嘴的定向结构。 [4] 该过程涉及无去溶剂化阳离子的插入/脱离，导致 MXene 片之间的层间距突然变化。 [5] 在此，通过将基于醋酸纤维素纤维的香烟过滤嘴 (CF) 浸入聚乙烯醇 (PVA) 的水溶液中，然后冷冻干燥并用 MXene 片材装饰来制造环境能量增强型太阳能蒸汽蒸发器。 [6] 更重要的是，三维 (3D) 交联石墨烯或/和 MXene 基材料，其中石墨烯或/和 MXene 片材互连成宏观的整体块状材料，可以实现出色的电磁干扰 (EMI) 屏蔽和微波吸收 (MA)性能，以及重量轻、卓越的机械性能等。 [7] 该过程涉及无去溶剂化阳离子的插入/脱离，导致 MXene 片之间的层间距突然变化。 [8] 多孔结构的构建可以有效解决MXene片材的自堆叠问题。 [9] 与 PTFE 的复合材料将有效缓解 MXene 片材的氧化。 [10] 介绍了 MXene 片材分层或剥落的努力。 [11] 通过浸入 AlCl 3 /HCl 溶液中以去除电绝缘的 AlOOH 纳米颗粒，以及交联 MXene 片材并将灯丝界面与铝离子融合，从而增强印刷的框架。 [12] 在这里，我们报告了大尺寸剥离的 Mo-MXene 片材，它为碳量子点 (CQD) 的装饰和受控的表面磷化（表示为 Mo-MX/C/P 杂化物）提供了平坦的柔性界面。 [13] , Ti3AlC2) 使用危险的 HF 或类似物，导致 MXene 片材在胶体分散体中具有氟末端和较差的环境稳定性。 [14] 由 CNT 触手交织而成的复合材料增强了导电性并防止了 Mxene 片材的重新堆叠。 [15] 在此，通过沉积聚磷酸铵 (APP)/聚乙烯亚胺 (PEI) 层、MXene 片材和聚己内酯 (PCL) 层，制备了具有阻燃和自愈性能的耐用 EMI 屏蔽苎麻织物。 [16] 增强的屏蔽能力主要由 m-MXene 网络中的高传导损耗、m-MXene 片材之间的多次反射以及 m-MXene 片材表面的极化效应引起的电磁吸收所主导。 [17] MXene 片材与纤维素纤维的紧密接触和充分吸附使电极在大面积上具有均匀的导电性和高稳定性。 [18] 开发了将 MXene 片材转化为具有优异电化学性能的 TiOF2 2D 片材。 [19] 这一突破是由于认识到 MXene 片材的边缘带正电。 [20] 硅/MXene 复合纸是通过真空过滤将硅纳米球共价锚定在基于 MXene 片材的高导电网络上合成的。 [21] 源自 MXene 和 NR 胶乳的负电荷的静电排斥力使 MXene 片材能够选择性地分布在 NR 颗粒的界面处，形成互连网络，以在低 MXene 含量下进行有效的电子传输和负载转移。 [22] Nafion 作为表面活性剂，通过过滤导致 MXene 片材有序的逐层沉积。 [23] 由于静电吸引效应，带正电的聚（二烯丙基二甲基氯化铵）（PDDA）长链会附着在带负电的 MXene 上，从而防止新剥离的 MXene 片材团聚并减少与钢球的碰撞。 [24] 在这里，我们回顾了 MXene 片材的大块组件的电气测量，并证明结果不仅在很大程度上取决于 MXene 的化学成分和结构，而且还取决于组件的形式（过滤、旋转浇铸或喷涂薄膜、压制圆盘） , 一个粒子等 [25] MoSe2 SSC 器件的能量/功率密度与所报道的分别使用石墨烯片、硅氧烷片和 MXene 片等二维材料的 SSC 相当甚至更高。 [26] 此外，具有高电导率的 MXene 片材可以增强对太赫兹波的响应能力。 [27] 反作用力场可以准确地描述 MXene 系统的化学性质，以深入了解 MXene 片材中的离子嵌入和水扩散以及测量这些结构的摩擦系数。 [28] 此外，通过理论计算和实验研究证实，这种“亲钾”MXene片材可以诱导钾成核，并在循环过程中引导钾在支架中均匀分布。 [29] 为了收集用于光催化的太阳能，我们制造了一种由具有二维 (2D) MXene 片的铁酸铋纳米粒子组成的纳米混合系统，即 BiFeO3 (BFO)/Ti3C2 (MXene) 纳米混合系统，以增强光催化活性。 [30]
2d Mxene Sheets
Herein, a highly stable composite is developed as a promising cathode by directly growing non-oriented H2V3O8 nanowires on 2D Mxene sheets. [1] [22] These 2D MXene sheets can be synthesized by selectively etching the main group element (A) from the ternary transition metal carbides/or nitrides called MAX (M: transition metals, A: main group element, X: C/or N) phase using different etchants such as hydrofluoric (HF) or lithium fluoride/hydrochloric acid (LiF/HCl) mixtures. [2] The molten salt treated products are delaminated and quasi-2D MXene sheets can be obtained. [3] Assembly of 2D MXene sheets into a 3D macroscopic architecture is highly desirable to overcome the severe restacking problem of 2D MXene sheets and develop MXene‐based functional materials. [4] 2D MXene sheets may buffer large volume changes and form a 3D conductive network to facilitate the electronic transfer of working electrodes. [5]在此，通过在二维 Mxene 片材上直接生长无取向 H2V3O8 纳米线，开发出一种高度稳定的复合材料作为有前途的阴极。 [1] [22] 这些 2D MXene 片可以通过从称为 MAX 的三元过渡金属碳化物/或氮化物（M：过渡金属，A：主族元素，X：C/或 N）中选择性蚀刻主族元素 (A) 来合成使用不同的蚀刻剂，例如氢氟酸 (HF) 或氟化锂/盐酸 (LiF/HCl) 混合物。 [2] 熔融盐处理后的产品分层，可以获得准二维 MXene 片材。 [3] 将 2D MXene 片材组装成 3D 宏观架构是克服 2D MXene 片材严重的重新堆叠问题并开发基于 MXene 的功能材料的理想选择。 [4] 2D MXene 片材可以缓冲较大的体积变化并形成 3D 导电网络，以促进工作电极的电子转移。 [5]

Herein, we report a novel and facile vapor phase polymerization (VPP) and spray-coating strategy towards the construction of a laminated film containing a PEDOT film and Ti3C2Tx MXene sheets on the fiber surface. [1] Although Ti3C2Tx MXene sheets are highly conductive, it is still a challenge to design highly stretchable MXene electrodes for flexible electronic devices. [2] A simple noncovalent chemical approach and hydrothermal method were used for effectively riveting Co3O4 nanocrystals to branched polyethylenimine (PEI) functionalized Ti3C2Tx MXene sheets to fabricate Co3O4@PEI/Ti3C2Tx MXene composites. [3] Herein, flexible piezoresistive pressure sensors are fabricated by treating the backbone of polyurethane (PU) sponge with chitosan (CS) to obtain positively charged CS@PU sponge, followed by dip-coating of negatively charged Ti3C2Tx MXene sheets. [4] Herein, a facile electrostatic self-assembly of SnO2 quantum dots (QDs) on Ti3C2Tx MXene sheets is proposed. [5]在此，我们报告了一种新颖且简便的气相聚合 (VPP) 和喷涂策略，用于在纤维表面构建包含 PEDOT 膜和 Ti3C2Tx MXene 片材的层压膜。 [1] 尽管 Ti3C2Tx MXene 片材具有高导电性，但为柔性电子设备设计高度可拉伸的 MXene 电极仍然是一项挑战。 [2] 使用简单的非共价化学方法和水热法将 Co3O4 纳米晶体有效地铆接到支化聚乙烯亚胺 (PEI) 功能化的 Ti3C2Tx MXene 片材上，以制备 Co3O4@PEI/Ti3C2Tx MXene 复合材料。 [3] 在此，柔性压阻式压力传感器是通过用壳聚糖（CS）处理聚氨酯（PU）海绵的骨架以获得带正电荷的 CS@PU 海绵，然后浸涂带负电荷的 Ti3C2Tx MXene 片材来制造的。 [4] 在此，我们提出了在 Ti3C2Tx MXene 片材上实现 SnO2 量子点 (QD) 的简单静电自组装。 [5]

Herein, two-dimension monolayer Ti3C2 MXene sheets were introduced to support PtNi octahedrons (PtNi@Ti3C2 MXene), which optimizes the activity and stability of PtNi nanoparticles (NPs) through interface interactions between PtNi and Ti3C2 MXene. [1] The high electrocatalytic performance of NiFe2O4/Ti3C2 composite is believed to be originated from a well-constructed nanoparticle-sheet interface, synergistic effect, and the high metallic conductivity of Ti3C2 MXene sheets. [2]在此，引入了二维单层 Ti3C2 MXene 片材以支持 PtNi 八面体 (PtNi@Ti3C2 MXene)，通过 PtNi 和 Ti3C2 MXene 之间的界面相互作用优化 PtNi 纳米粒子 (NPs) 的活性和稳定性。 [1] NiFe2O4/Ti3C2 复合材料的高电催化性能被认为源于结构良好的纳米颗粒-片材界面、协同效应和 Ti3C2 MXene 片材的高金属导电性。 [2]

With well-managed surface patterning geometry and printing ink quality control, the surface microchannels constrained MXene suspensions and leveraged microforces to facilitate preferential alignment of MXene sheets via layer-by-layer additive depositions. [1] Herein, MXene/bacterial cellulose fiber (BCF) hybrid films with effectively expanded interlayer spacing between re-stacked few-layered MXene sheets via homogeneous intercalation of BCF nanospacer were designed and prepared.
