Abstract

The invention provides an ultra-flexible self-generating yarn, an all-fiber-based ultra-flexible temperature-difference self-generating fabric and a preparation method thereof. The ultra-flexible self-generating yarn adopts P-type thermoelectric material composed of PEDOT:PSS and ionic liquid to coat and modify the fiber or yarn, which significantly improves the film-forming property of PEDOT:PSS, and also enhances the flexibility of the yarn. improve its thermoelectricity. The N-type thermoelectric material and the above-mentioned P-type thermoelectric material are coated adjacent to the surface of the yarn substrate, and are connected by electrodes to form a series thermoelectric path. The flexibility, thermoelectricity and stability of power generation of the all-fiber-based ultra-flexible thermoelectric self-generating fabrics thus prepared are significantly improved, providing an effective way for the all-fiber-based ultra-flexible thermoelectric self-generating fabrics. Therefore, as a power source, it has high promotion and application value in the fields of sensor device power supply, smart clothing, and wearable electronic devices.
