摘要

有效和环保的空气过滤器对于保护公众健康至关重要，因为颗粒物污染已经对人类健康造成了永久性损害。本研究采用共混纺丝工艺制备了一种独特的聚偏氟乙烯/角蛋白驻极体过滤器，具有可靠的PM0.3还原性能和综合性能。更具体地说，添加天然羊毛角蛋白显著增加复合纤维膜的孔隙结构和表面电荷。角蛋白与聚偏氟乙烯协同作用得到的纤维膜具有良好的过滤性能，质量因子为0.04662 /Pa，压降低至127 Pa，颗粒去除率高达99.731%。这种驻极体材料的发展为设计高效去除PM0.3的环保型空气过滤器提供了新的途径。

A Novel Polyvinylidene Fluoride/Keratin Electret Filter With Comprehensive Performance and High-Efficiency PM0.3 Removal

Effective and environmentally friendly air filters to preserve public health are essential given the particle matter pollution epidemic that has permanently damaged human health. This study used blending spinning to create a unique polyvinylidene fluoride/keratin electret filter with reliable PM0.3 reduction and comprehensive features. More specifically, adding keratin derived from natural wool significantly increased composite fibrous membranes’ pore structure and surface charge. Keratin and polyvinylidene fluoride work together synergistically to produce a fiber membrane that exhibits good filtration performance with a quality factor of 0.04662 /Pa, a low pressure drop of 127 Pa, and a high particle removal capacity of 99.731%. The development of this electret material provides a new approach for the design of environmentally friendly air filters for efficient removal of PM0.3.
