Provided are an proton conducting polymer electrolyte membrane and a manufacturing method thereof which control the proton conducting nanochannel size and proton conductivity by phase separation improvement of a polar aprotic solvent in casting the proton conducting polymer electrolyte membrane.

Ion conductive polymer electrolyte membrane having ion channel size controlled according to phase separation improvement effect of polar solvent during casting of ion conductive polymer electrolyte membrane, and preparation method therefor

The present invention relates to a proton conductive nanocomposite membrane and a method for manufacturing same, the proton conductive nanocomposite membrane having polyhedral oligomeric silsesquioxane (POSS) having a proton donor and POSS having a proton acceptor introduced into an aromatic hydrocarbon polymer membrane having a sulfonyl group. The nano-composite membrane of the present invention has both the POSS having a proton donor and the POSS having a proton acceptor added thereto, and thus protons (cations) that are generated are easily hopped in an ion channel by means of hydrogen bonding, and thus ionic conductivity is increased. In addition, the POSS used in the present invention has a very small size, and thus hardly obstructs proton migration in the ion channel in the polymer membrane, and thus excellent proton conductivity may be enabled. In addition, the proton conductive nanocomposite membrane by the present invention exhibits excellent mechanical strength even though the degree of sulfonation of the polymer membrane is increased.
