Hydrophobic Polyurethane(疏水聚氨酯)研究综述
Hydrophobic Polyurethane 疏水聚氨酯 - It was observed that hydrophobic polyurethane and epoxy resin coatings showed weak anti-asphaltene performance with low R aa values where they have reduced asphaltene deposition 10% and 48. [1] A hydrophobic polyurethane (PU) was altered to obtain a hydrophilic characteristic using the graft polymerization of 2-(dimethylamino)ethyl methylmethacrylate (DAMA) onto the PU surface and the subsequent ionization of the dimethylamino group on poly(DAMA). [2] In order to solve the problem of dust accumulation on the fin surface of a mine air cooler, a method of preparing super-hydrophobic polyurethane (SPU) coating based on waste cooking oil (WCO) was proposed. [3] In this article, a superhydrophobic polyurethane (PU) sponge with exceptional flame-retardant property, was fabricated by coating polydopamine (PDA) through one-step polymerization and surface treatment with hexamethyl disilazane (HMDS). [4]据观察，疏水性聚氨酯和环氧树脂涂料的抗沥青质性能较弱，R aa 值较低，沥青质沉积减少 10% 和 48%。 [1] 使用甲基丙烯酸 2-(二甲氨基)乙酯 (DAMA) 接枝聚合到 PU 表面并随后将聚 (DAMA) 上的二甲氨基离子化来改变疏水性聚氨酯 (PU) 以获得亲水特性。 [2] 为解决矿用空冷器翅片表面积尘问题，提出了一种基于废弃食用油（WCO）制备超疏水聚氨酯（SPU）涂层的方法。 [3] 在本文中，通过一步聚合和六甲基二硅氮烷（HMDS）表面处理的方法涂覆聚多巴胺（PDA），制备出具有优异阻燃性能的超疏水聚氨酯（PU）海绵。 [4]
hydrophobic polyurethane sponge 疏水聚氨酯海绵
Using a simple dipping method, a novel the magnetically driven hydrophobic polyurethane sponge (MHPS) was synthesized in this work. [1] Herein, we demonstrated a facile method for the fabrication of magnetic and superhydrophobic polyurethane sponge with water contact angle of 159° as an adsorbent for cleanup the marine oil spill pollution. [2] The oil absorption ability of the magnetic superhydrophobic highly-porous melamine sponge was much better than that of the magnetic superhydrophobic polyurethane sponge with relatively low porosity. [3] Furthermore, the d-PDA/Fe(III) coating could act as an intermediate layer in the preparation of hydrophobic polyurethane sponge for highly efficient oil/water separation. [4]在这项工作中，采用简单的浸渍方法，合成了一种新型的磁驱动疏水聚氨酯海绵（MHPS）。 [1] 在此，我们展示了一种制备磁性和超疏水聚氨酯海绵的简便方法，该海绵具有 159° 的水接触角，可作为清除海洋溢油污染的吸附剂。 [2] 磁性超疏水高孔三聚氰胺海绵的吸油能力明显优于具有较低孔隙率的磁性超疏水聚氨酯海绵。 [3] 此外，d-PDA/Fe(III)涂层可以作为制备疏水性聚氨酯海绵的中间层，用于高效的油/水分离。 [4]
hydrophobic polyurethane foam
This paper proposes a novel application of the closed-cell one-component hydrophobic polyurethane foam (HPUF) to stabilize the swelling soil. [1] We have developed an improved and effective method to immobilize lipase on hydrophobic polyurethane foam (PUF) with different modifications. [2] Superhydrophobic polyurethane foam (PUF) is prepared by surface coating of halloysite nanotubes. [3]本文提出了一种闭孔单组分疏水聚氨酯泡沫 (HPUF) 用于稳定膨胀土壤的新应用。 [1] 我们开发了一种改进且有效的方法，将脂肪酶固定在经过不同修饰的疏水聚氨酯泡沫 (PUF) 上。 [2] 超疏水聚氨酯泡沫（PUF）是通过埃洛石纳米管的表面涂层制备的。 [3]
hydrophobic polyurethane coating
Thus, hydrophobic polyurethane coatings are highly effective in reducing the chloride permeability and water penetration values, which helps to eliminate corrosion and lengthen the service life of structures located in an aggressive marine environment. [1] Here, we show that by means of this experimental approach, it was possible to quantitatively monitor the influence of humidity on the viscoelasticity of two different thin and hydrophobic polyurethane coatings representative of those typically used to protect materials from processes like weathering and wear. [2]因此，疏水性聚氨酯涂料在降低氯化物渗透率和水渗透值方面非常有效，这有助于消除腐蚀并延长位于侵蚀性海洋环境中的结构的使用寿命。 [1] 在这里，我们表明，通过这种实验方法，可以定量监测湿度对两种不同的薄且疏水的聚氨酯涂层粘弹性的影响，这些涂层代表通常用于保护材料免受风化和磨损等过程的影响。 [2]
