Electrospinning PAN/TiO2 Nanofiber-based Composite Functional Film with Waterproof-breathable and High UV Resistance Performance

采用静电纺丝法`及膜后处理法,以聚丙烯腈(PAN)、纳米二氧化钛、硝酸银和全氟辛基三氯硅烷为原料,制备了可穿戴的具有抗紫外性能的防水透湿微孔膜并进行相关表征。研究了不同含量的TiO2和Ag纳米材料对PAN纳米纤维抗紫外及防水透湿性能的影响。实验结果表明,PAN纳米纤维膜中引入纳米二氧化钛和银纳米粒子具有紫外波区UVB和UVA全屏蔽的性能,且复合膜疏水改性后防水透湿性能优异。

Wearable, waterproof and breathable microporous membranes with anti-ultraviolet property were prepared by using polyacrylonitrile(PAN), nano titanium dioxide, silver nitrate and perfluorooctyltrichlorosilane as raw materials, via electrospinning method and membrane post-treatment, and the as-prepared functional nanofibrous membranes were tested by related characterizations. The effects of different amount of TiO2 and Ag nanoparticles on the anti-ultraviolet and waterproof-breathable properties of PAN nanofibrous composite membranes were studied. The experimental results showed that the introduction of TiO2 and Ag nanoparticles into PAN-based films could endow the property of full shielding in UVB and UVA ultraviolet regions, and the composite membranes would have the excellent waterproof and breathable properties after hydrophobic modification.
