Abstract：

In this paper, the full-carbon poly (styrene methyl styrene) backbone main chain was synthesized via ATRP reaction. Naphthalene and long alkyl quaternary ammonium salt cationic groups were used as functional side links, then the corresponding anion exchange membranes were prepared. The microphase separation structure in the membranes was observed by electron microscopy. The results of small angle X-ray scattering also showed that the membranes have a large ion domain, which could be attributed to the significant difference in hydrophilicity between the main chain and the side chain. The ionic conductivity of the membrane PSMS-NAPMQA-5 was 98.53mS/cm at 80 oC. The maximum single-cell power density was 144.13 mW/cm2. All the prepared membranes showed good chemical stability after 1000 h treatment with 80 oC 2 mol/L NaOH solution
