Abstract

The invention relates to a method for preparing a flexible carbon nanotube-polyaniline thermoelectric device, comprising: adding carbon nanotubes and sodium dodecylbenzenesulfonate to HCl solution, ultrasonication, cell crushing, and then adding aniline, ultrasonication , stirred under ice-bath conditions to obtain a carbon nanotube-aniline dispersion, add dropwise the HCl solution of ammonium persulfate, and obtain a carbon nanotube-polyaniline dispersion after the reaction; the fabric is put into a sodium hydroxide solution and heated, and then put Stir in water at 60-90°C, take it out, dry it, add it to the carbon nanotube-polyaniline dispersion, ultrasonicate it, dry it, repeat the steps of fabric impregnation and drying; cut the dried polyester into rectangular strips , alternately fixed on the flexible substrate, and parallel connection of rectangular strips with conductive fibers, that is. The method of the invention is simple, and the prepared carbon nanotube-polyaniline composite thermoelectric fabric has the advantages of light weight, good flexibility and foldability, and can be assembled into a large-scale portable thermoelectric device.

Description

technical field [0001] The invention belongs to the field of preparation of thermoelectric devices, in particular to a preparation method of flexible carbon nanotube-polyaniline thermoelectric devices. Background technique [0002] Modern life makes people increasingly inseparable from wearable and portable devices such as watches, bracelets, hearing aids, and mobile phones. How to provide continuous energy supply for these devices is an urgent problem to be solved. Traditional dry battery energy supply is not permanent, needs to be replaced frequently, and is relatively bulky and cannot be bent and folded. Batteries are also bulky, inflexible, and prone to contamination. So people turned their attention to new energy sources, such as solar energy and thermoelectric energy. Compared with solar energy, thermoelectric devices use temperature differences to generate electricity, which is more in line with the concept of sustainable energy utilization. Although inorganic the...
