摘要
A novel sulfonated polyimide containing triphenyl methane as the polymer electrolytes for fuel cell appliaction was successfully synthesized.The sulfonic acid function was only attached at the para positions on the pendant phenyl rings due to the novel sulfonated diamine structures designed.The sulfonated polymers are very soluble in common organic solvents,such as dimethyl sulfoxide,N,N’-dimethylacetamide,and can be readily cast into tough and smooth films from solutions.The membranes show excellent hydrolytic and oxidative stabilities and can be potentially used as the proton-exchange membranes for fuel-cells.
