In Situ Electropolymerization in Mesoporous Carbon: A Universal Method for Improving the Electrochemical Performance of Polymer Electrode Materials

Although polymer electrode materials have great potential to achieve a long cycle life, they are often difficult to prepare as a well-distributed composite electrode because of the severe aggregation of polymer chains. In situ electropolymerization in porous carbon is an effective approach to tackling this issue. The monomers play an important role in improving the efficiency of electropolymerization and the performance. In this work, the effects of monomers on monomer conversion and electrochemical performance are investigated using seven monomers with different structures and solubilities. All monomers show enhanced electrochemical performance, revealing the universality of monomers in the in situ electropolymerization in nanopores of mesoporous carbon.
