Abstract

Electrochromic devices have found widespread use in automotive, aerospace, and architectural implementations. This talk will detail our recent research of liquid crystalline compositions in which the selective reflection can be tuned, broadened, and switched by mechanical, thermal, or electrical stimuli. Enabled by the modularity of the formulation of the cholesteric liquid crystal phase, filters can be prepared throughout the electromagnetic spectrum (VIS, NIR, SWIR, MWIR).
