Abstract

According to the electric heating fabric based on the copper nanowires and the preparation method of the electric heating fabric based on the copper nanowires, the electric heating fabric based on the copper nanowires comprises a base material layer and a protective layer which are arranged in a stacked mode, the base material layer is loaded with the copper nanowires, and / or a copper nanowire functional layer is arranged between the base material layer and the protective layer. According to the copper nanowire electric heating fabric, the protection layer is arranged on the base material layer loaded with the copper nanowires or the protection layer is arranged on the copper nanowire functional layer, the protection layer is used for isolating air, the copper nanowires can be protected against oxidation, the copper nanowires can be prevented from falling off from the base material layer, and therefore the electric heating performance of the copper nanowire electric heating fabric is enhanced.

Description

technical field [0001] The invention relates to the technical field of electrothermal materials, and relates to a copper nanowire electrothermal fabric and a preparation method thereof. Background technique [0002] It is also a metal material. The conductivity of copper nanowires is second only to that of silver nanowires, and the difference in conductivity is only 6%. Moreover, the reserves of copper are very rich. In nature, the reserves of copper are 1,000 times that of silver, and the price is seven times that of silver. one tenth. One-dimensional (1D) inorganic nano-copper materials exhibit more unique properties than other structures in optics, thermo-thermal, electronics, and chemistry, and thus have great potential in the fields of medicine, aviation, and microelectronics. application prospects. [0003] Copper nanowires have gradually become the focus of optoelectronic research. Using copper nanowires to modify flexible fabrics can make such composites both flexi...
