Fig. 4: Color reprogramming and self-healing of CLCEs.
From: Visible-light-programmed patterning in dynamically bonded cholesteric liquid crystal elastomer
Scheme (a) and corresponding images (b) of the stretching-mode CLCEs color “write-erase” mechanism. c Photographs of the CLCE stretched after self-healing. d Stress–strain curves of the original CLCE and the self-healing CLCEs after thermal pressing for different times. e Cross-section SEM of the interface at the bonding site of CLCEs with Se–LC after 12 h of hot pressing.
