Polyelectrolyte Layer(聚电解质层)研究综述
Polyelectrolyte Layer 聚电解质层 - We theoretically investigate the feasibility of enhancing the reverse electrodialysis power generation in nanochannels by covering the surface with a polyelectrolyte layer (PEL). [1] The article dealt with an analytic study on the electroosmotic flow and mass transport of an electro neutral solute through polyelectrolyte layer (PEL)-coated canonical nanopore under the imposed alternative current electric field for Maxwell fluids. [2] Herein, we proposed a new type of surface-charged MXene (SC-MXene) membrane for water desalination, which was facilely fabricated by laminar stacking of MXene nanosheets and subsequent surface-coating with polyelectrolyte layer. [3] Nanochannels covered with a polyelectrolyte layer (PEL) are recently shown to increase the power generation by reverse electrodialysis (RED) considerably. [4] Although there are conjectures, it is not yet fully understood where the polyelectrolyte layering takes place when modifying porous membranes, either within the pores or on top of the porous material. [5] To amplify the fluorescence signal we used polyelectrolyte layers to control the distance between metal nanoparticles and fluorophore. [6] It was concluded that the polyelectrolyte layers are mixed in the entire shell of the capsules with a dissolved CaCO3 core. [7] The formation of the polyelectrolyte layers led to charge reversal of the carrier and the saturated PDADMAC and PSS layers stabilized the dispersions, in particular, their resistance against salt-induced aggregation was especially excellent. [8] This delay was dependent on the number of polyelectrolyte layers. [9] FINDINGS PAH/PSS multilayers, show a polarity similar to water with DX/PSS as top layer, decreasing to I1/I2 ratios similar to organic solvents as the number of polyelectrolyte layers assembled on top increases. [10] The successful construction of the drug delivery system relied on tea saponin grafted on chitosan (TS/CTS) via formatted ester bonds or amido bonds as a polyelectrolyte layer of PEGylated dihydromyricetin-loaded liposomes (DMY lips), which achieved controlled release of DMY in weak acidic and neutral physiological environments. [11] Polyelectrolyte layers of poly(diallyl dimethyl ammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS) are deposited onto the Al surface using a layer-by-layer (LbL) adsorption technique. [12] We demonstrate how to tailor membrane pore size and thickness using polyelectrolyte layer-by-layer assembly by alternately applying two strong polyelectrolytes, PDADMAC and PSS, to a polysulfone substrate while systematically controlling the polyelectrolyte and salt concentrations in the deposition solution. [13] The results reveal that the growth of polyelectrolyte layer in nanochannels is quite different from that on flat substrates. [14] An alternative has been proposed, in which the electrodes are coated with a polyelectrolyte layer, also of suitable polarity. [15] Via a simple 3-step layer-by-layer coating process, few-layered MoS2 nanoflakes are incorporated into the polyelectrolyte layer, and open the organic solvent pathways which are otherwise closed without MoS2. [16] The soft microchannel, also called as the polyelectrolyte-grafted microchannel, is denoted as a rigid microchannel coated with a polyelectrolyte layer (PEL) on its surface. [17] Here, we cost-efficiently prepared large-area Au nanocube arrays (NCAs) using only the electrostatic forces between colloidal Au nanocubes and polyelectrolyte layers. [18] Surface chemistry strategies for coating nanocrystals with smooth or rough shells are detailed; specific examples include mesoporous silica and metal-organic framework shells for porous (rough) coatings and polyelectrolyte layer-by-layer wrapping for "smooth" shells. [19] Manufacturing such “iontronic” devices generally involves classical thin film processing of polyelectrolyte layers and insulators followed by application of electrolytes. [20] Another approach that has been tested is based on coating the carbon with polyelectrolyte layers, converting them into “soft electrodes” (SEs). [21] The number of polyelectrolyte layers, the deposition technology, the nature of the interactions between the components and the chosen components, as well as the produced systems, make LbL a versatile technique. [22] Using the method of time-lapse confocal microscopy, we observed a prolonged lag phase, dependent on the number of polyelectrolyte layers. [23] A soft nanochannel involves a soft interface that contains a polyelectrolyte layer (PEL) sandwiched between a rigid surface and a bulk electrolyte solution. [24] Then, polyelectrolyte layers composed of poly(allylamine hydrochloride) (PAH) and poly(sodium 4-styrenesulfonate) (PSS) and doxorubicin hydrochloride (DOX) were capped on Fe3O4 NCs to construct the Fe3O4 NC/PAH/PSS/DOX hybrid nanostructures via LBL method. [25] For the first time, it was shown that primary modification of the Au surface influences the rate of the multilayer assembling and the shape of appropriate dependence of the SPR signal on the number of polyelectrolyte layers. [26] Soft nanochannels are defined as nanochannels with a polyelectrolyte layer (PEL) on the rigid walls. [27] We show that an increase in the thickness of the polyelectrolyte layer (PEL) increases the transverse electrostatic potential, which upon interacting with the externally applied electric field alters the flow dynamics non-trivially in a rotating platform. [28] Three compositions were considered: with MWCNTs incorporated between polyelectrolyte layers; with MWCNTs inserted into the hollow of the microcapsule; and with MWCNTs incorporated simultaneously into the hollow and between polyelectrolyte layers. [29] The main challenge is controlling the electrophoretic translocation velocity of DNA and one remedy is covering the inner wall of the nanopore with a polyelectrolyte layer (PEL). [30] Incorporation of magnetite nanoparticles into polyelectrolyte layers renders HC-MFs visible for MRI and induces the red-shift in their transmission spectra. [31] The core is considered to have an arbitrary charge, and the charge of the polyelectrolyte layer is assumed to be homogeneous and independent of the electrolyte properties. [32]我们从理论上研究了通过用聚电解质层 (PEL) 覆盖表面来增强纳米通道中反向电渗析发电的可行性。 [1] 本文讨论了在麦克斯韦流体施加的交流电场下，电中性溶质通过聚电解质层 (PEL) 涂覆的规范纳米孔的电渗流动和质量传输的分析研究。 [2] 在此，我们提出了一种用于海水淡化的新型表面带电 MXene (SC-MXene) 膜，该膜通过 MXene 纳米片的层状堆叠和随后的聚电解质层表面涂层轻松制造。 [3] 最近显示，覆盖有聚电解质层 (PEL) 的纳米通道可显着增加反向电渗析 (RED) 的发电量。 [4] 尽管存在猜想，但尚未完全了解当改性多孔膜时，聚电解质层发生在哪里，无论是在孔内还是在多孔材料的顶部。 [5] 为了放大荧光信号，我们使用聚电解质层来控制金属纳米颗粒和荧光团之间的距离。 [6] 得出的结论是，聚电解质层在胶囊的整个壳中与溶解的 CaCO3 核混合。 [7] 聚电解质层的形成导致载体的电荷反转，饱和的 PDADMAC 和 PSS 层稳定了分散体，特别是它们对盐诱导聚集的抵抗力特别出色。 [8] 这种延迟取决于聚电解质层的数量。 [9] 发现 PAH/PSS 多层膜显示出与水相似的极性，以 DX/PSS 作为顶层，随着组装在顶部的聚电解质层数的增加，I1/I2 比率降低至类似于有机溶剂的 I1/I2 比率。 [10] 该药物传递系统的成功构建依赖于茶皂素通过格式化的酯键或酰胺键接枝在壳聚糖上（TS/CTS）作为聚电解质层的聚乙二醇化二氢杨梅素负载脂质体（DMY Lips），实现了DMY在弱环境中的控释。酸性和中性生理环境。 [11] 使用逐层 (LbL) 吸附技术将聚 (二烯丙基二甲基氯化铵) (PDADMAC) 和聚 (4-苯乙烯磺酸钠) (PSS) 的聚电解质层沉积到铝表面上。 [12] 我们演示了如何使用聚电解质逐层组装来调整膜孔径和厚度，方法是在聚砜基材上交替应用两种强聚电解质 PDADMAC 和 PSS，同时系统地控制沉积溶液中的聚电解质和盐浓度。 [13] 结果表明，纳米通道中聚电解质层的生长与平面基板上的生长完全不同。 [14] 已经提出了一种替代方案，其中电极涂有同样具有合适极性的聚电解质层。 [15] 通过简单的 3 步逐层涂覆工艺，将少层 MoS2 纳米薄片结合到聚电解质层中，并打开有机溶剂通路，否则在没有 MoS2 的情况下会关闭。 [16] 软微通道，也称为聚电解质接枝微通道，表示为在其表面涂有聚电解质层（PEL）的刚性微通道。 [17] 在这里，我们仅使用胶体金纳米立方体和聚电解质层之间的静电力经济高效地制备了大面积金纳米立方体阵列 (NCA)。 [18] 详细介绍了用光滑或粗糙外壳涂覆纳米晶体的表面化学策略；具体的例子包括用于多孔（粗糙）涂层的介孔二氧化硅和金属有机框架壳和用于“光滑”壳的聚电解质逐层包裹。 [19] 制造这种“离子电子”设备通常涉及聚电解质层和绝缘体的经典薄膜处理，然后是电解质的应用。 [20] 另一种经过测试的方法是在碳上涂上聚电解质层，将它们转化为“软电极”（SE）。 [21] 聚电解质层的数量、沉积技术、组件与所选组件之间相互作用的性质以及所生产的系统，使 LbL 成为一种通用技术。 [22] 使用延时共聚焦显微镜的方法，我们观察到一个延长的滞后期，这取决于聚电解质层的数量。 [23] 软纳米通道涉及软界面，其中包含夹在刚性表面和本体电解质溶液之间的聚电解质层 (PEL)。 [24] 然后，将由聚（烯丙胺盐酸盐）（PAH）和聚（4-苯乙烯磺酸钠）（PSS）和盐酸阿霉素（DOX）组成的聚电解质层覆盖在 Fe3O4 NCs 上，通过以下方法构建 Fe3O4 NC/PAH/PSS/DOX 杂化纳米结构LBL 方法。 [25] 首次表明，Au 表面的初级改性会影响多层组装的速率以及 SPR 信号对聚电解质层数的适当依赖性的形状。 [26] 软纳米通道被定义为在刚性壁上具有聚电解质层 (PEL) 的纳米通道。 [27] 我们表明，聚电解质层 (PEL) 厚度的增加会增加横向静电势，这在与外部施加的电场相互作用时会在旋转平台中显着改变流动动力学。 [28] 考虑了三种组合物： 在聚电解质层之间加入 MWCNT；将多壁碳纳米管插入微囊的中空；并且MWCNTs同时结合到中空和聚电解质层之间。 [29] 主要挑战是控制 DNA 的电泳易位速度，一种补救措施是用聚电解质层 (PEL) 覆盖纳米孔的内壁。 [30] 将磁铁矿纳米颗粒结合到聚电解质层中，可以使 HC-MF 对 MRI 可见，并引起其透射光谱的红移。 [31] 核心被认为具有任意电荷，并且聚电解质层的电荷被认为是均匀的并且与电解质性质无关。 [32]
Charged Polyelectrolyte Layer
Electrophoresis of core-shell composite soft particles possessing hydrophobic inner core grafted with highly charged polyelectrolyte layer (PEL) has been studied analytically. [1] The rigid walls of the undertaken channel are coated with ion and fluid penetrable charged polyelectrolyte layers (PELs). [2]已经分析研究了具有接枝有高电荷聚电解质层（PEL）的疏水内核的核壳复合软颗粒的电泳。 [1] 采用的通道的刚性壁涂有离子和流体可穿透的带电聚电解质层 (PEL)。 [2]
Outer Polyelectrolyte Layer
In addition, the inner core and the outer polyelectrolyte layer (PEL) bear pH-regulated basic and acidic functional groups, respectively. [1] We consider a typical situation where the outer polyelectrolyte layer (PEL) carries zwitterionic functional group (e. [2]此外，内核和外聚电解质层 (PEL) 分别带有 pH 调节的碱性和酸性官能团。 [1] 我们考虑了一种典型的情况，即外聚电解质层 (PEL) 带有两性离子官能团 (e. [2]
Conjugated Polyelectrolyte Layer
Here CdS photocatalysts are coated by non-conjugated polyelectrolyte layers, and the influence of the polymer on charge transfer over CdS is explored. [1] In addition, the roughness of ZnO barely changed after coating with PFEO SO3 Li, and the surface became more hydrophobic, which demonstrates that the thin conjugated polyelectrolyte layer exhibits good adhesion with both ZnO and the active layer. [2]在这里，CdS 光催化剂被非共轭聚电解质层覆盖，并探讨了聚合物对 CdS 上电荷转移的影响。 [1] 此外，在涂覆PFEO SO3 Li后，ZnO的粗糙度几乎没有变化，并且表面变得更加疏水，这表明薄的共轭聚电解质层与ZnO和活性层均表现出良好的粘附性。 [2]
Adsorbed Polyelectrolyte Layer
The hydrodynamic thickness of the adsorbed polyelectrolyte layer (δH) and electrophoretic mobility (EPM) of particles as a function of concentration ratios of the two polyelectrolytes were measured to clarify the effect of negatively charged molecules on the structure of the positively charged adsorbed layer at various ionic strengths. [1] The response of the adsorbed polyelectrolyte layer was monitored upon changing the electrolyte pH and ionic strength. [2]测量了吸附聚电解质层的流体动力学厚度 (δH) 和颗粒的电泳迁移率 (EPM) 作为两种聚电解质浓度比的函数，以阐明带负电荷的分子在不同条件下对带正电荷的吸附层结构的影响。离子强度。 [1] 在改变电解质 pH 值和离子强度时监测吸附的聚电解质层的响应。 [2]
Dense Polyelectrolyte Layer 致密聚电解质层
Space electroosmotic thrusters (EOTs) are theoretically investigated in a soft charged nanochannel with a dense polyelectrolyte layer (PEL), which is considered to be more realistic than a low-density PEL. [1] We theoretically study the hydrodynamic dispersion by fully developed electroosmotic flow in soft slit microchannels of dense polyelectrolyte layer (PEL). [2]理论上，空间电渗推进器 (EOT) 在具有致密聚电解质层 (PEL) 的软带电纳米通道中进行研究，这被认为比低密度 PEL 更现实。 [1] 我们通过充分发展的电渗流在致密聚电解质层 (PEL) 的软狭缝微通道中从理论上研究流体动力学分散。 [2]
