PROTON CONDUCTIVE MATERIAL
PROTONENLEITFÄHIGES MATERIAL
Abstracts:
A proton-conductive material is provided which has a high proton conductivity even without moistening and does not elute in water. A proton conductive material comprises a proton source polymer and a proton channel polymer, wherein at least one selected from the group consisting of the proton source polymer and the proton channel polymer is a polymer containing an aromatic ring, and at least a portion of the polymer, containing the aromatic ring has a stacked structure formed by π-π interactions, and a proton conductive material comprises a proton source crosslinked polymer, wherein the proton source crosslinked polymer is a polymer containing a main skeleton containing a proton source group and an aromatic ring , and having a crosslinked structure containing a proton channel, and wherein at least a part of the proton source crosslinked polymer has a stacked structure formed by π-π interactions.
Es wird ein protonenleitfähiges Material bereitstellet, das auch ohne Befeuchtung eine hohe Protonenleitfähigkeit aufweist und nicht in Wasser eluiert. Ein protonenleitfähiges Material umfasst ein Protonenquellen-Polymer und ein Protonenkanal-Polymer, wobei mindestens eines ausgewählt aus der Gruppe bestehend aus dem Protonenquellen-Polymer und dem Protonenkanal-Polymer ein Polymer ist, das einen aromatischen Ring enthält, und wobei mindestens ein Teil des Polymers, das den aromatischen Ring enthält, eine durch π-π-Wechselwirkungen gebildete Stapelstruktur aufweist, und ein protonenleitfähiges Material umfasst ein Protonenquellen-vernetztes Polymer, wobei das Protonenquellen-vernetzte Polymer ein Polymer ist, das ein Hauptgerüst, das eine Protonenquellengruppe und einen aromatischen Ring enthält, und eine vernetzte Struktur aufweist, die einen Protonenkanal enthält, und wobei mindestens ein Teil des Protonenquellen-vernetzten Polymers eine durch π-π-Wechselwirkungen gebildete Stapelstruktur aufweist.
