Patent ID: 7402361

Claim:
An ion conductor structural body having a high ion conductivity and excellent mechanical strength, comprising: (a) a polymer matrix; (b) a solvent capable of functioning as a plasticizer and having a boiling point of more than 70° C. and a solubility parameter of 15.0 to 30.0 (J/cm% 3 ) 1/2 ; and (c) an electrolyte, wherein a ratio of a weight of the solvent to a weight of the polymer matrix is 1 to 20, wherein a content of the electrolyte to that of the solvent is from 0.5 to 3 mol/dm 3 , wherein the polymer matrix (a) comprises a polymer chain having at least a first segment represented by formula (1) and a second segment represented by formula (2), a main chain portion of the polymer chain and a side chain portion of the first segment having an orientation property, and the polymer matrix has a cross-linked structure wherein R 1 and R 2 are, respectively, H or an alkyl group of 2 or fewer carbon atoms, A is a group having at least a polyether group, and R 3 is a group having at least an alkyl group of 6 or more carbon atoms, wherein R 3 in the general formula (1) is a straight chain alkyl group of 6 to 22 carbon atoms or an alkyl benzyl group having a straight chain alkyl group of 6 to 22 carbon atoms, and wherein a molecular weight ratio of the alkyl group of R 3 to the polyether group of A is from 0.05 to 3.0, wherein R 4 and R 5 are, respectively, H or an alkyl group of 2 or fewer carbon atoms, and B is a group comprising at least a polar group selected from the group consisting of a polyether group, a cyano group, an amino group, an amido group and a carbonate group.
