Abstract

The invention belongs to the field of conductive macromolecule-inorganic nano-structure composite thermoelectric materials, and relates to a method for preparing carbon nano tube/poly (3-hexyl) thiophene (CNT-P3HT) composite thermoelectric materials. The method comprises the steps of adding zirconia grinding balls and the moderate amount of oxidants into a zirconia ball grinding tank, adding the CNT, conducting mixing uniformity, then dropwise adding the moderate amount of 3-HT monomers, placing the sealing ball grinding tank in a ball grinding machine to conduct ball grinding after the ball grinding tank is sealed, after finishing the ball grinding, transferring the balls and reactants in the ball grinding tank to a beaker, adding deionized water into the beaker to conduct stirring, washing black products in the beaker by the deionized water, conducting centrifuging until a supernatant is colorless, and then conducting vacuum drying. The prepared CNT/P3HT composite powder is compressed to be block-shaped composite materials. The process is simple and environmentally friendly, and large-scale production can be easily achieved. The synthetized CNT/P3HT composite thermoelectric materials can be widely applied to thermoelectric cooling and power generation equipment with the temperature lower than 150 DEG C, and the market prospect is wide.

Description

technical field [0001] The invention belongs to the field of conductive polymer-inorganic nanostructure composite thermoelectric materials, and relates to a preparation method of a CNT / P3HT composite thermoelectric material. Background technique [0002] Thermoelectric materials are functional materials that can realize direct conversion between thermal energy and electrical energy through the transport of carriers (holes or electrons) in solids. The application of thermoelectric materials does not require the use of transmission components, the structure is simple, the size can be made small, there is no noise during operation, no waste, and no pollution to the environment, and this material also has excellent characteristics such as long service life and reliable performance. . Therefore, thermoelectric materials are a class of environmentally friendly materials with broad application prospects and are considered to be very competitive energy alternative media in the futu...
