Poly(3-hexylthiophene)-b-poly(ethylene glycol) methacrylate was synthesized to obtain the polymer system having both ionic and electronic conductivity. The molecular weight of poly(3-hexylthiophene)(P3HT) and poly(ethyleneglycolmethacrylate) (PEGMA) was controlled by Grignard metathesis and ATRP, respectively. Then, block copolymer containing P3HT and PEGMA was synthesized via click reaction. The structure of the block copolymer was systematically investigated by NMR, GPC and FT-IR. It was found that the ionic conductivity of the block copolymer is 1.5x10-6 S/cm. We believe that this block copolymer could be a promising cathode material for lithium ion-battery. |
