Electronically conjugated functional covalent organic frameworks for electroactive artificial muscles

Abstract

A pre‐designed functional π‐conjugated nanoporous covalent organic frameworks (COFs) are suggested to develop a high‐performance electrode for electroactive ionic soft actuators. In-depth structural characterization confirm the structural integrity of the developed active materials. Nanoporous structural configuration of COFs acted as nanoreactors for boosting the transportation and accommodation of oppositely charged ions in presence of available electrolytes during the switching of an alternating current input signal. As a results, the soft electroactive actuators show fast rise times, short phase delays, strong blocking force, high bending displacement, and ultralong durability.
