▎ 摘　　要

NOVELTY - Preparing a high-efficiency fiber-based thermoelectric energy supply material, comprises (i) preparing a thermoelectric solution containing thermoelectric materials, (ii) immersing the fiber base material in the resultant solution, taking it out and drying to obtain a fiber base material with a thermoelectric material adsorption capacity of 10-40%, then, arranging the electrodes on the upper and lower surfaces of the fiber substrate to obtain a fiber-based self-power generation layer, (iii) adding the photothermal nano-particles to the viscose solution containing the binding material and mixing them uniformly to obtain colloidal photothermal material, then uniformly coating the colloidal photothermal material on the upper surface of the fiber-based self-power generation layer obtained in resultant step, performing drying treatment and colloidal photothermal material forms a photothermal film on the upper surface. USE - The method is useful for preparing a high-efficiency fiber-based thermoelectric energy supply material. ADVANTAGE - The material: has excellent thermoelectric performance, high power generation efficiency, flexibility, and high application value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for high-efficiency fiber-based thermoelectric energy supply material comprising fiber-based self-generating layer and a photo-thermal film set on the upper surface of the fiber-based self-generating layer. The fiber base self-generating layer comprises a fiber base material absorbed with thermoelectric material and an electrode arranged on the upper and lower surfaces of the fiber base material. The photo-thermal film contains photo-thermal nano-particles and bonding material.
