Anisotropic Mechanochromism
In article number 2310658, Suk‐kyun Ahn and co‐workers create cholesteric liquid crystal elastomers (CLCEs) with slanted helices via direct ink writing. Notably, the anisotropic mechanochromic response of the printed CLCE to being stretched relative to the printing direction is observed. The anisotropic mechanochromism enables the creation of a unique strain sensor displaying...
Cholesteric liquid crystal elastomers (CLCEs) are unique anisotropic rubbers that can change their structural color in response to various stimuli such as heat, chemicals, electric fields, and mechanical stress. Methods such as anisotropic deswelling and surface alignment have been adopted to prepare CLCEs; however, they have limitations in creating spatially controlled CLCE geometries. In this work,...
