Abstract:

Polymer/liquid crystal composite films can be electrically switched between a zero-field opaque state and an activate clear state. The physical performance of polymer/liquid crystal composite films has led to their use in a wide range of applications, such as smart windows, bistable devices and optical diffusers. In order to widen the applications, we have fabricated four kinds of switchable anti-peeping devices, which has contributed to our privacy protection.

Keywords: polymer/liquid crystal composite films ; switchable anti-peeping devices; privacy protection; viewing angle
