Binder is an essential component in constructing electrodes for various devices. Especially, binding of nanoparticles in electrochemical devices affects highly the device performance. In this work, we report the synthesis of intrinsically conductive, solution-processable polymer adhesives by treating polyaniline with ternary additives and their excellent performance as binders for supercapacitor electrodes. With an optimized composition and no heat treatment process or conductive fillers, the conductive adhesive (Q-PANI) had a conductivity of 0.9 S cm−1 and 20−25% better adhesive ability than polyvinylidene fluoride insulating binder. Q-PANI appeared good redox properties in an acidic electrolyte. As a result, Q-PANI as a binder was demonstrated as an excellent binder for obtaining the enhanced electrode performance of both pseudocapacitive and electric double-layer capacitive nanomaterials (carbon black). |
