Abstract
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.
