preparation example Construction

[0046] Such as figure 1 Shown, the preparation method of polypyrrole / zirconium carbide / polyurethane composite fiber film of the present invention comprises the steps:

[0047] (1) Add zirconium carbide and polyurethane to the mixed solution of dimethylacetamide and tetrahydrofuran to obtain zirconium carbide / polyurethane mixed spinning solution.

[0048] (1-1), dissolving polyurethane in dimethylacetamide and tetrahydrofuran mixed solution, stirring to obtain polyurethane spinning solution;

[0049] (1-2), then a certain amount of zirconium carbide is added in the dimethylacetamide solution to obtain a zirconium carbide dispersion;

[0050] (1-3). Finally, the polyurethane spinning solution is mixed with the zirconium carbide dispersion to obtain a zirconium carbide / polyurethane mixed spinning solution.

[0051](2) Prepare the zirconium carbide / polyurethane composite fiber membrane by using an electrospinning machine to prepare the zirconium carbide / polyurethane mixed spinni...

Embodiment

[0072] The preparation method of the polypyrrole / zirconium carbide / polyurethane composite fiber membrane of the present embodiment comprises the steps:

[0073] (1) Mix dimethylacetamide and tetrahydrofuran with a mass ratio of 1:1, add polyurethane and continuously stir for 8 hours at room temperature with a magnetic stirring device to obtain a polyurethane spinning solution with a solid content of 25%.

[0074] (2) Next, a certain amount of zirconium carbide was added into the dimethylacetamide solution, and then ultrasonically oscillated in a water bath at 35° C. for 30 minutes to obtain a zirconium carbide dispersion with a solid content of 25%.

[0075] (3) Finally, the polyurethane spinning solution and the zirconium carbide dispersion are mixed to obtain a zirconium carbide / polyurethane mixed spinning solution, wherein the zirconium carbide dispersion accounts for 4% of the mass sum of the zirconium carbide dispersion and the polyurethane spinning solution.

Abstract

The invention provides a polypyrrole / zirconium carbide / polyurethane composite fiber membrane as well as a preparation method and application thereof. The composite fiber membrane comprises polyurethane, nano zirconium carbide dispersed in the polyurethane and polypyrrole coating the surface of the polyurethane. The preparation method comprises the following steps of adding the zirconium carbide and the polyurethane into a mixed solution of dimethylacetamide and tetrahydrofuran to obtain a zirconium carbide / polyurethane mixed spinning solution, preparing a zirconium carbide / polyurethane composite fiber membrane by adopting an electrostatic spinning machine, preparing the polypyrrole / zirconium carbide / polyurethane composite fiber membrane by adopting an in-situ polymerization process, performing washing, and performing drying. According to the invention, the nano zirconium carbide and polypyrrole with the photothermal conversion efficiency are combined with a polyurethane material with excellent mechanical properties, so that the fiber membrane material which has a photothermal conversion function and certain mechanical properties and air permeability and is light and thin is obtained; and in addition, the membrane can convert light energy into heat energy and is further applied to the fields of clothes, buildings, seawater desalination and the like.

Description

technical field [0001] The invention belongs to the technical field of light-to-heat conversion materials and composite fiber manufacturing, and specifically relates to a polypyrrole / zirconium carbide / polyurethane composite fiber film with light-to-heat conversion function 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] Photothermal conv...
