Abstract:
1. An organic domain/inorganic domain hybrid material comprising: an organic domain comprising at least one water-soluble organic polymer having a plurality of functional groups, wherein each functional group is independently selected from the group consisting of an anionic functional group and a cationic functional group, and an inorganic domain, said organic domain and said inorganic domain being chemically bonded to each other through said functional groups of said organic polymer, said inorganic domain comprising a plurality of inorganic bridges having both ends thereof which are, respectively, chemically bonded to said functional groups of said organic polymer, wherein each inorganic bridge is independently represented by the formula (1): wherein each M independently represents a divalent metal atom selected from the group consisting of beryllium, magnesium, calcium, strontium, barium, copper, zinc, nickel, iron, manganese, chromium and cobalt, and each of R 1 to R 4 independently represents a hydrogen atom, a hydroxyl group, a monovalent organic group, a monovalent, siloxane linkage-containing group, or a single bond which is linked to any one of R 1 to R 4 of an adjacent inorganic bridge through at least an oxygen atom, wherein each of r, s and t is independently an integer of 1 or more, and u is an integer of 0 or more, provided that, when both ends of said inorganic bridge are, respectively, bonded to cationic functional groups, u is an integer of 1 or more, and wherein, when at least one end of said inorganic bridge is bonded to an anionic functional group, the bonding is made through a divalent metal atom selected from the group consisting of beryllium, magnesium, calcium, strontium, barium, copper, zinc, nickel, iron, manganese, chromium and cobalt, wherein, when at least a part of said organic domain is comprised of at least one organic polymer having an anionic functional group and optionally a cationic functional group, the weight ratio of said organic domain to said inorganic domain is less than 1.0, and wherein, when at least a part of said organic domain is comprised of at least one organic polymer having an anionic functional group and optionally a cationic functional group, or when said organic domain is comprised of at least one organic polymer having a cationic functional group and having no anionic functional group and when the weight ratio of said organic domain to said inorganic domain is less than 1.0, not all divalent metal atoms of said inorganic domain are simultaneously calcium atoms.
