Description

technical field [0001] The invention relates to a method for manufacturing a flexible thermoelectric element, which belongs to the technical field of electronic materials and devices. Background technique [0002] A thermoelectric material is a material that converts thermal energy to electrical energy through the transport of its own carriers (holes or electrons) in a solid state. Due to its small size, no vibration, no noise, no pollution, no wear, no moving parts, maintenance-free, and no pollution, thermoelectric conversion technology has unique advantages in heat energy utilization. Conductive polymers have the advantages of low thermal conductivity, light weight, low cost, easy synthesis and processing, and are a potential thermoelectric material. The common conductive polymers of conjugated polymers mainly include polyaniline (PANi), polypyrrole (PPy), polythiophene (PTh) and their derivatives. Composite thermoelectric materials based on conductive polymers can be p...
