Abstract A series of polyvinylidene fluoride (PVDF)/layered double hydroxide (LDH) composite membranes were prepared via phase inversion method, in which the presence of LDH promotes the formation of β-phase PVDF. This work reveals the key role of hydrogen-bonds on the nucleation mechanism and crystallization behavior of PVDF. The composite membranes exhibit improved porosity and hydrophilicity, leading to an enhanced antifouling property against proteins.

氢键诱导β-聚（偏二氟乙烯）的成核和生长

摘要 采用相转化法制备了一系列聚偏二氟乙烯（PVDF）/层状双氢氧化物（LDH）复合膜，其中LDH的存在促进了β相PVDF的形成。这项工作揭示了氢键对 PVDF 的成核机制和结晶行为的关键作用。复合膜表现出改善的孔隙率和亲水性，从而增强了对蛋白质的防污性能。
