Randomized trial uncovers the distribution of dynamic bonds in liquid-crystal elastomers, indicating insights for improved function.
Key Points
This work aims to understand the structural characteristics of diselenide-containing liquid-crystal elastomers (LCEs) and the distribution of dynamic bonds within their networks.
Utilized anomalous wide-angle X-ray scattering (AWAXS) for structural analysis of dynamic LCEs.
Synthesize main-chain LCEs using aza-Michael chemistry with diselenide bonds as crosslinkers.
Conducted coarse-grained X-ray scattering simulations to support AWAXS data.
The diselenide-containing crosslinks are heterogeneously distributed within the LCE networks.
Differences in reactivities between chain extender monoamine and crosslinker diamine affect diselenide bond distribution.
Insights into network structure link molecular organization to functional performance.
