The invention has the beneficial effects that: the carbon fiber and the polyester fabric are perfectly combined, the problem of poor physical and chemical properties of the existing carbon crystal heating body is avoided, and the advantages of the polyester fiber and the carbon fiber heating body are achieved. The introduction of the carbon nano tube not only improves the conductivity of the fiber, but also is beneficial to forming a compact layer on the surface of the fiber by the polypyrrole, thereby further improving the electrical property of the modified fabric.
Before MWCNTs deposition is carried out on the surface of the cotton fiber, the MWCNTs are subjected to surface modification treatment by adopting H2SO4/HNO3 (3: 1) SO as to introduce hydrophilic functional groups such as carboxyl, hydroxyl and the like. After the MWCNTs layer is deposited on the surface of the fiber, the PPy layer is constructed in an interfacial polymerization mode. The MWCNTs surface active group can form a hydrogen bond with the PPy unit, and can generate pi bond interaction with the PPy due to natural aromaticity of the MWCNTs, so that the PPy layer deposited on the surface of the fiber is more compact.
The fiber fabric exhibits excellent mechanical stability and maintains good electrical properties in cyclic tests of twisting, bending, folding and the like. And the interface treatment is carried out on the polyester yarns by adopting an alkali subtraction method, so that the limit composite fastness of the polyester yarns is improved, and the polyester yarns are easier to print and dye. The carbon nano tube is coated with the polyester yarn fiber to prepare the high-heat-conductivity and heat-flexibility heating wire, so that the preparation difficulty of the heating wire is reduced, and the preparation period is shortened; compared with a metal heating wire, the metal heating wire has light and thin hand feeling, strong air permeability and good folding resistance; compared with the preparation method of mixing non-metal composite heating materials, such as carbon fiber and polymers, the preparation method has simple process and controllable process, and the prepared composite fabric not only has the conductivity of the carbon nano tube, but also can keep the mechanical property of the matrix fabric.
The image layer is printed by heat-resistant pigments, such as organic pigments, and efficient mass production can be realized by means of printing. Compared with the existing carbon fiber/carbon crystal heating body (the working temperature is 95-150 ℃), when 3.5V-7.5V voltage is applied to the two ends of the heating layer, the working temperature is usually 20-75 ℃, and the heat-resistant pigment can be kept stable in the temperature range, so that the phenomena of fading, discoloration, decomposition and the like cannot occur. In addition, even if the heat accumulation effect of the heat generating layer is considered, the heat accumulation effect is increased by 20-40% on the basis of the highest working temperature, and the existing pigment can completely meet the requirement.
Because the composite fiber fabric is adopted to replace an electrode structure, the limitation of the thickness of the lithium battery and the correlation of the process difficulty is broken through, a thinner composite heating structure with a power supply can be manufactured under the same process condition, the application range of the product is further improved, and the appearance is more concise and attractive. The spiral fiber lithium battery can realize tensile property without an elastic substrate, thereby reducing the weight and the volume of the device and improving the specific capacity and the energy density of the device. Has good flexibility, easy weaving, tensile resistance and higher durability.
The insulating layer on the heating layer is set to be in a relief effect, and the electrochromic layer is pasted on the relief layer, so that local color change can be carried out by matching with the content of an image. Specifically, a PWM modulation module (in the prior art, such as a breathing lamp on a smart device, only the voltage regulation function of the present invention is adopted) is connected to an input terminal of the electrochromic layer, and the period according to the pulse sequence is 2560ms, that is, about 2.5 s; the driving power with 2.5s period approximate to sine can be output after the integral operation of the integral module, the voltage at two ends of the electrochromic layer is driven to change, the electrochromic layer is enabled to change color circularly, and the different colors and the same color of the electrochromic layer are changed alternately with different depths. Thereby producing unexpected visual effects, such as maple leaf images, and realizing green, yellow and red color conversion through electrochromism to present different seasons. For example, wind blows over a large tree, with leaves alternating between dark green and light green. And for example, waterfall water flow, flood lake surface and other blue and white alternating water flow effects.
