Abstract

Fluorine-free waterproof and breathable membranes (WBMs) with exceptional protective capabilities, efficient moisture-vapor transmission, and environmentally benign characteristics have demonstrated indispensable application value in multiple fields. Herein, polyacrylonitrile/isophorone diisocyanate/aminosilicone oil (PAN/IPDI/ASO) nanofibrous membranes were prepared by electrospinning and coated with a fluorine-free hydrophobic coating. The obtained composite membranes exhibited excellent comprehensive properties with a hydrostatic pressure of 64.4 kPa, a water vapor permeability (WVP) of 6.4 kg·m^–2·d^–1, and a tensile strength of 11.6 MPa. Moreover, the PAN/IPDI-1/ASO-2 nanofibrous membranes maintained their water repellency and mechanical property under strong acidic and alkaline conditions and remained hydrophobic even after 60 abrasion cycles and 30 min of water ultrasonic cleaning. These fluorine-free and environmentally friendly PAN/IPDI/ASO WBMs have broad application prospects in outdoor sports equipment, medical protection, and other fields.

无氟疏水涂层改性聚丙烯腈/二异氰酸酯纳米纤维膜在纺织品中的应用

无氟防水透气膜（WBMs）具有优异的防护能力、高效的水汽传输和环保特性，在多个领域显示出不可或缺的应用价值。采用静电纺丝法制备了聚丙烯腈/二异氰酸酯异佛酮/氨基硅油（PAN/IPDI/ASO）纳米纤维膜，并包覆了一层无氟疏水涂层。复合膜的静水压力为64.4 kPa，水蒸气渗透率（WVP）为6.4 kg·m-2·d-1，抗拉强度为11.6 MPa，综合性能优良。此外，PAN/IPDI-1/ASO-2纳米纤维膜在强酸性和强碱性条件下仍保持其拒水性和力学性能，即使经过60次磨损和30 min的水超声清洗仍保持疏水性。这些无氟环保的PAN/IPDI/ASO wbm在户外运动装备、医疗防护等领域有着广阔的应用前景。
