Semicrystalline Ion Gels: Synthesis, Characterization, and Application in Strain Sensors

초록

Highly crystalline copolymers composed of crystalline and amorphous units were utilized to fabricate ion gels. Poly(docosyl acrylate-r-methyl acrylate) copolymers, synthesized via free radical polymerization, were solution-blended with ionic liquids ([EMI][TFSI]) to prepare ion gels. The resulting ion gels exhibited high crystallinity, and the crystallized domains of docosyl acrylates functioned as cross-links. We conducted a systematic investigation of the thermal and mechanical properties of the ion gels and studied their feasibility for self-healing and strain sensor applications. A comparison with previous results highlights the importance of amorphous units in achieving mechanically tough and self-healable ion gels.
