▎ 摘　　要

NOVELTY - Organic/inorganic hybrid composite proton exchange membrane comprises: 0.001-10 wt.% of an inorganic material which is a graphene derivative with two-dimensional structure; and 99.999-90 wt.% of the organic material containing a polymer material with sulfonic acid. USE - The organic/inorganic hybrid composite proton exchange membrane is useful as fuel barrier material. ADVANTAGE - The membrane: exhibits low permeability; and reduce methanol crossover while maintaining high proton conductivity at low levels of benzene graphene sulfonate.
