ABSTRACT:
Disclosed are an organic domain/inorganic domain hybrid material comprising an organic domain comprising at least one water-soluble organic polymer having anionic and/or cationic functional groups, and an inorganic domain, the organic and inorganic domains being chemically bonded to each other through the functional groups, the inorganic domain comprising inorganic bridges, each independently comprising at least one Si atom, at least two O atoms and at least one divalent metal atom, wherein the Si atom and the O atoms together form at least one siloxane linkage arranged longitudinally of the inorganic bridge, wherein each divalent metal atom is ionically bonded to the O atoms of the siloxane linkages positioned adjacent to the divalent metal atoms, wherein, when at least a part of the organic domain is comprised of at least one organic polymer having an anionic functional group and optionally a cationic functional group, the organic domain/inorganic domain weight ratio is less than 1.0; and the use thereof as a hydrophilicity reagent and an antibacterial/antifungal reagent.
