Enhanced conductivity of novel star branched liquid crystalline copolymer based on poly(ethylene oxide) for solid polymer electrolytes

► Novel star branched amphiphilic liquid crystalline copolymers are prepared by atom-transfer radical polymerization. ► Lamellar structures are achieved by cooperative assembly of hydrophobic mesogen-containing polymethacrylate and the amorphous hydrophilic TPEO nanoscale aggregation. ► The ionic conductivity has been improved greatly by incorporation of the mesogens.
