Patterned nanofiber air filters with high optical transparency, robust mechanical strength, and effective PM_2.5 capture capability.

ABSTRACT: PM_2.5, due to its small particle size, strong activity, ease of the attachment of toxic substances and long residence time in the atmosphere, has a great impact on human health and daily production. In this work, we have presented patterned nanofiber air filters with high optical transparency, robust mechanical strength and effective PM_2.5 capture capability. Here, to fabricate a transparency air filter by a facile electrospinning method, we chose three kinds of patterned wire meshes with micro-structures as negative receiver substrates and directly electrospun polymer fibers onto the supporting meshes. Compared with randomly oriented nanofibers (named "RO NFs" in this paper) and commercially available facemasks, the patterned air filters showed great mechanical prope
