Although ionic liquid (IL) is getting more attention due to its unique properties, such as low vapor pressure, nonflammability, and high ionic conductivity, it has significant obstacle, a physical form. It flows, as its name suggests, limiting its application. Block copolymer ion gels, with improved mechanical integrity and ordered microstructure, were successfully synthesized with several IL-philic midblocks such as poly(methyl methacrylate), poly(ethyl acrylate), and poly(ethylene oxide). It is inevitable to have lower conductivity with higher block copolymer loading, so a new way for balancing modulus and conductivity is required. In this work, surface-modified aramid nanofiber (S-ANF) can minimize block copolymer loading by interacting with its IL-phobic block, minimizing conductivity loss. Physical properties and electrochemical performances were examined with respect to S-ANF and block copolymer loading.
