An organic-inorganic hybrid nanofiber characterized by comprising a crystalline polymer filament made of a polymer having a straight-chain polyethyleneimine skeleton, and a silica covering said crystalline polymer filament.
A method for producing an organic-inorganic hybrid nanofiber characterized by comprising the steps of
- (1) obtaining a crystalline polymer filament of a polymer having a straight-chain polyethyleneimine skeleton by dissolving the polymer having the straight-chain polyethyleneimine skeleton in a solvent, followed by precipitation in the presence of water, and
- (2) covering said crystalline polymer filament with a silica by contacting said crystalline polymer filament with an alkoxysilane in the presence of water.
A method for producing an organic-inorganic hybrid structure characterized by comprising the steps of
- (1′) obtaining a crystalline polymer filament of a polymer having a straight-chain polyethyleneimine skeleton and at the same time, obtaining a hydrogel formed from said crystalline polymer filament, by dissolving the polymer having the straight-chain polyethyleneimine skeleton in a solvent, followed by precipitation in the presence of water, and
- (2′) covering the crystalline polymer filament in said hydrogel with a silica by contacting the hydrogel formed from said crystalline polymer filament with an alkoxysilane in the presence of water.
