摘要： 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 nanocomposite 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.

摘要： The present invention relates to a sulfonated polyetheretherketone (sPEEK) nanocomposite film containing silsesquioxane and exhibiting excellent proton conductivity and mechanical strength, and a method for manufacturing the same. The nanocomposite film of the present invention has excellent conductivity since multiple sulfonic acid groups as a proton source exist in POSS used as a filler. In addition, the POSS used in the present invention is very small, having a size of 1-2 nm, and thus hardly obstructs the migration of protons in the ion channel in the polymer membrane, thereby realizing excellent proton conductivity. In addition, the proton conductive nanocomposite film by the present invention shows excellent mechanical strength even though the degree of sulfonation of sulfonated polyetheretherketone is increased.
