Problems solved by technology

It can be seen from the above documents and patents that the current intelligent temperature-regulating fabrics still have the following shortcomings: 1) Traditional fabrics such as cotton and linen textiles cannot dynamically match human infrared radiation based on the principle of human infrared radiation, so that traditional fabrics can only be single The control of the thermal comfort environment of the human body
2) Traditional fabrics are thick and heavy, and are not as comfortable as intelligent temperature-adjustable fabrics when worn on the human body
3) Most of the temperature-adjusting fabrics currently on the market use electric heating or hair dryers to achieve heat preservation or cooling, which consumes energy and has low efficiency, and can only achieve heat preservation or cooling functions
4) The temperature-adjustable fabrics currently reported in the literature add nanoparticles or coatings on the basis of traditional fabrics, which affect comfort
5) If the external energy is consumed, the temperature cannot be self-regulated, and the wearability is poor, etc., it is necessary to design the fabric structure to prepare a fabric with excellent temperature regulation performance and good wearability

Abstract

The invention discloses a temperature-adjustable fabric based on carbon nanotubes and a preparation method thereof. The temperature-adjustable fabric includes: an inner structure layer, which includes a carbon nanotube layer and a metal layer covered on the carbon nanotube layer, and the infrared light emission rate of the metal layer is lower than that of the carbon nanotube layer. rate; and, the outer structural layer, which at least covers the first surface and the second surface of the inner structural layer, and the first surface and the second surface are arranged opposite to each other in the thickness direction of the inner structural layer, so The outer structural layer has a hole structure and can transmit infrared rays. The preparation method includes: depositing a metal layer on the surface of the carbon nanotube film to form an inner structure layer; and at least the outer structure layer covers the first surface and the second surface of the inner structure layer. The invention does not consume any other energy, and utilizes the difference in the infrared emissivity of the inner structure layer in the front and back directions to automatically adjust the temperature according to the change of the environment's temperature and temperature, and at the same time realize the effect of heat preservation or cooling.

Description

technical field [0001] The invention relates to a temperature-adjustable fabric, in particular to a temperature-adjustable fabric based on carbon nanotubes and a preparation method thereof, belonging to the technical field of new nanometer materials. Background technique [0002] In recent years, with the development of textile scientific research technology and people's demand for higher quality of life, fabrics have gradually developed in the direction of multi-function and intelligence. Fabrics have an additional active role in adapting to physiological needs and environmental changes, a function known as "active thermal comfort regulation". Nowadays, intelligent temperature-adjustable fabrics have been gradually applied to clothing manufacturing, which has a significant effect on improving thermal comfort and wearability. But so far, most of the smart temperature-regulating fabrics realize the temperature-regulating function of the fabrics through electric heating or fa...
