聚合物共混物提供了一种简单的途径来获得由单个组分产生的具有各种协同性能的材料。聚偏氟乙烯-共六氟丙烯（PVDF-HFP）是一种疏水性聚合物，由于其高热稳定性、机械强度和耐候性，正在聚合物电解质、膜和耐热结构材料中寻找新的应用。在本报告中，制备了PVDF-HFP和聚合物刷的共混物，具有增强的吸水性和抗蛋白质性，这是用于食品和生物应用的膜的重要要求。高分子刷由聚甲基丙烯酸甲酯主链（与PVDF-HFP相混）和亲水聚乙二醇（PEG）刷链组成。聚乙二醇链通过聚合物刷结构的掺入，不仅增强了聚合物刷结构的吸水性和蛋白质吸附阻力，而且通过基质形成了分布均匀的共混组分形态，这一点可以通过观察聚合物刷从基质中选择性提取后的形貌得到证明。(C) 2012 Elsevier b.v.版权所有
Polymeric blends provide a facile route to obtaining materials with various synergistic properties arising from the individual components. Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), a hydrophobic polymer, is finding new applications in polymer electrolytes, membranes, and heat-resistant structural materials owing to its high thermal stability, mechanical strength, and weatherability. In this report, blends of PVDF-HFP and polymer brush were prepared with enhanced water uptake and protein resistance, which are important requirements for membranes used in food and biological applications. Polymer brush is composed of poly(methyl methacrylate) main chains, which are miscible with PVDF-HFP, and hydrophilic poly(ethylene glycol) (PEG) brush chains. Incorporation of PEG chains through the polymer brush structure not only enhanced water uptake and protein adsorption resistance but also produced a well-distributed morphology of the blending components through the matrix as evidenced by observation of the morphology after selective extraction of polymer brush from the matrix.
