Nanofiber-based transparent film with controllable optical transparency adjustment function for versatile bionic applications

As a new favorite in the field of smart materials, smart windows, with visual stimulus sensing functions, have attracted extensive attention for their high transparency, sensitive response to environmental stimulus, and reversible changes in light transmittance. In this paper, the PVA-co-PE nanofiber film, which was completely opaque like paper, was used as filling phase and reacted with water-soluble N-vinyl-2-pyrrolidone (NVP) by...
