Abstract

The invention provides a zirconium carbide / polypyrrole-polyurethane composite fiber and a preparation method and application thereof. The zirconium carbide / polypyrrole-polyurethane composite fiber comprises a polyurethane matrix and zirconium carbide / polypyrrole composite particles, the zirconium carbide / polypyrrole composite particles comprise zirconium carbide and polypyrrole, and polypyrrole is doped with bis (trifluoromethylsulfonyl) lithium imide. The preparation method comprises the following steps that the zirconium carbide / polypyrrole composite particles are firstly synthesized, polyurethane is dissolved in dimethylformamide and stirred to obtain a polyurethane solution, the zirconium carbide / polypyrrole composite particles are dispersed in the polyurethane solution, and a wet spinning process is carried out. According to the zirconium carbide / polypyrrole-polyurethane composite fiber and the preparation method and application thereof, polypyrrole mainly has relatively strong absorption capability on near-infrared light; and zirconium carbide can absorb near-infrared light, and further can efficiently absorb visible light; and polypyrrole has a photo-thermal conversion function and an electro-thermal conversion function, and the zirconium carbide / polypyrrole composite particles are filled into polyurethane fibers, so that the fiber material with a light absorption heating function and an electrified heating function is prepared.

Description

technical field [0001] The invention belongs to the technical field of composite fibers, and in particular relates to a zirconium carbide / polypyrrole-polyurethane composite fiber and its preparation method and application. Background technique [0002] In winter, down jackets for thermal insulation purposes can only maintain the basic heat for people to survive. Insulation based on equipment such as air conditioning and heating is another strategy for people to cope with cold climates to maintain a constant body temperature and normal activities. But the use of air conditioning and heating will bring serious environmental hazards, such as the hole in the ozone layer, the greenhouse effect and so on. Therefore, in order to reduce the use of air conditioning and heating, textiles with better thermal insulation functions have certain development prospects. [0003] Polypyrrole is a semiconductor material with both photothermal and electrothermal conversion functions. Althoug...
