Typical applications of polymer-dispersed of liquid crystal (PDLC) films include large and flexible information &splays and windows with electronically controlled transmission. Whenever these applications are intended for outdoor usage as, for example, when the films are to be applied to automobile sunroofs, selection criteria for the materials and choice of preparation method become important in order to satisfy the environmental temperature and humidity extremes. This paper reviews and compares different technologies for preparing PDLC films, giving special emphasis to their microstructure and ability to exhibit good electro-optic performance over an extended temperature range.
