摘要:
A silica nanofiber/metal oxide nanocrystal composite is produced by a method including associating a polymer having a linear polyethyleneimine skeleton in a water-based medium in the presence of ice, adding alkoxysilane to the water-based medium obtained in the above step to form a composite nanofiber including the associate and silica that covers the associate, while the fiber spontaneously forms a disc-shaped network structure, a step of depositing a metal oxide on a surface of the fiber by mixing the disc-shaped structure obtained in the above step with a hydrolyzable metal compound, and a step of calcining the disc-shaped. structure obtained in the step above to form a silica nanofiber through removal of the polymer in the fiber, to convert the metal oxide into a nanocrystal, and to bond the nanocrystal to the fiber. When zinc oxide is used as the metal oxide, the composite functions as a luminous body.

摘要:
A silica nanofiber is derived from a crystalline polymer filament of a polymer including straight chain polyethyleneimine backbones, which is capable of forming a water-insoluble crystal in the presence of water molecules at room temperature, and the crystalline polymer filament in the silica concentrates metal ions, thereby realizing a composite nanofiber including metals or metal ions in the silica. Furthermore, the composite nanofiber of the present invention can be easily produced by fixing a polymer structure in the silica as the scaffold for metal ions and concentrating metal ions at the scaffold or reducing the metal ions. Furthermore, a metal-containing silica nanofiber can be easily obtained by removing a polymer component from the composite nanofiber, the composite nanofiber association, and the complex nanofiber structure. These nanofibers can be assembled and integrated, and the assembled or integrated association or structure can realize various shapes.
