Overview

Randomized trial demonstrates distinct strategies for flexible chain incorporation in liquid crystal elastomers, indicating varying material properties.

Key Points

  • This research aims to explore the effects of flexible chain incorporation strategies on the properties of liquid crystal elastomers (LCEs).
  • Constructed a base LCE network using a thiol-ene ‘click’ reaction with specific crosslinkers and mesogenic units.
  • Developed two series of LCEs incorporating flexible chains through substitution and insertion strategies.
  • Analyzed the impact of these strategies on network topology and material properties.
  • Both incorporation strategies effectively reduced the glass transition temperature and enhanced confined ordering.
  • Substitution yielded a recovery rate >75% at moderate compositions, while excessive substitution increased crystallinity, decreasing recovery.
  • Insertion improved strength and actuation; moderate insertion allowed full recovery, excessive insertion disrupted network integrity.
