The invention discloses micro-nano complex fiber materials of a kind of loaded optic catalyst and preparation method thereof.Polyacrylonitrile micrometer fibers are made using wet spinning technology, one layer of conducting high polymers object polyaniline is grown by in-situ polymerization on polyacrylonitrile micrometer fibers surface again, one layer of polyacrylonitrile nanofiber containing photochemical catalyst presoma is covered on its surface by electrostatic spinning process, forms the micro-nano complex fiber material with visible light-responded photo-catalysis capability.The micro-nano complex fiber material of loaded optic catalyst provided by the invention has many advantages, such as large specific surface area, to pollutant strong adsorption, under visible light can be with degradation of contaminant.Meanwhile photochemical catalyst composite fibre provided by the invention solves the problems such as powder photocatalyst is difficult to recycling and flexible carrier of photocatalyst intensity difference, can not weave, and has widened the application field of material. |
