We introduce novel alkylated ion-conductive polymers which are applicable for PEMFC membranes. Alkylated polymers were synthesized through a condensation polymerization adopting alkylated monomers. The alkylated monomers were synthesized via a facile method based on the radical polymerization technique. The merit of this method is simplicity in producing alkylated monomers. To probe the effect of alkylation of sPAS on morphology and thermal properties, we investigated thermal properties including the glass transition temperatures (Tg) and thermal degradation behaviors, transport properties such as methanol diffusion coefficient and the proton conductance, morphology, and surface tensions. Based on the physical data, we will explain the alkylation effect on the PEMs in terms of surface property and morphology of membranes. |
