Energy & Actuator

The primary technology of next-generation wearable electronics pursues the development of highly deformable and stable systems.

A crucial strategy in the molecular design of polymer gelators is copolymerization of PMMA and IL-insoluble low glass transition temperature (Tg) polymers that can be deformed and effectively dissipate applied strains. Highly stretchable (elongation limit ≈850%), mechanically robust (elastic modulus ≈3.1 × 105 Pa), and deformation durable (recovery ratio ≈96.1% after 500 stretching/releasing cycles) gels are obtained by judiciously adjusting the molecular characteristics of polymer gelators and gel composition.
