제목 Synthesis of Poly(acrylic acid)-based Bottlebrush Polymers by RAFT and ROMP toward Binders for Silicon Anodes
초록 Poly(acrylic acid)s have been recognized as potential binders for silicon anode based Li-ion batteries since carboxylic acid groups of PAA can offer strong interactions with silicon surface. In silicon anodes, polymeric binders are desired to provide adhesion and to dissipate mechanical stress during repeated volume change. In this regards branched polymers are suggested to be better candidates than linear polymers because the mechanical stress received from volume changes can be distributed effectively through multiple anchoring points. Herein, we synthesized a series of PAA based bottlebrush polymers by combination of RAFT and ROMP. Several molecular parameters including the length of the backbone, side-chains and grafting density have been varied to investigate the impact of these parameters on the electrochemical performance of binders. We believe exploiting a chain topology can be a useful strategy to develop a novel polymeric binder with high capacity and cycling stability
