Abstract

The invention discloses a preparation method of an electric heating textile based on carbon nanotubes / silver nanowires. The preparation method comprises the steps that the carbon nanotubes and the silver nanowires are dispersed in deionized water containing polyoxyethylene dodecyl sulfate; polyacrylic resin is dissolved in a warm ethanol solution, intermittent ultrasonic treatment is carried out after heating and uniform stirring, and uniformly-dispersed dispersion liquid is obtained; a textile is immsersed into the carbon nanotube / silver nanowire dispersion liquid to be cooled to room temperature, drying treatment is carried out, and dipping and drying are repeated for 3-5 times to obtain the textile based on the carbon nanotubes / silver nanowires; and the textile based on the carbon nanotubes / silver nanowires is sheared, copper adhesive bands are attached to the two ends to lead out a wire, and the wire is externally connected with a voltage regulator and a power source. According tothe obtained electric heating textile based on the carbon nanotubes / silver nanowires, the bonding degree of the carbon nanotubes / silver nanowires and the textile is increased, and the bonding stability can be kept in the repeated washing process.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for preparing electrically heated textiles based on carbon nanotubes / silver nanowires. Background technique [0002] Electric heating textiles are functional textiles that combine exogenous heating materials with textiles for active heat generation and heat transfer. Electric heating elements are generally heating wires, carbon fiber heating materials and graphene materials. Carbon fiber filaments are widely used in electrically heated textiles because of their high heating efficiency and low cost, but they also have disadvantages such as uneven heating and easy breakage. [0003] The emergence of conductive nanomaterials such as graphene, carbon nanotubes and one-dimensional metal nanowires provides a good opportunity for the further development of electrically heated textiles. Carbon nanotubes (CNTs) not only have the advantages of high heating efficiency of carbon ...
