Super-flexible self-generating yarn, all-fiber-based super-flexible thermoelectric self-generating fabric and preparation method thereof

The invention provides a super-flexible self-generating yarn, a full-fiber-based super-flexible thermoelectric self-generating fabric and a preparation method thereof. According to the super-flexible self-generating yarn, a P-type thermoelectric material composed of PEDOT: PSS and ionic liquid is adopted to conduct coating modification on fibers or yarns, the film-forming property of PEDOT: PSS is remarkably improved, the yarn flexibility is enhanced, and meanwhile the thermoelectric property of the yarns is improved. An N-type thermoelectric material and the P-type thermoelectric material are coated on the surface of a yarn base material in an adjacent mode and are connected through electrodes to form a series thermoelectric path. The flexibility, thermoelectricity and power generation stability of the prepared full-fiber-based super-flexible thermoelectric self-power-generating fabric are remarkably improved, and an effective way is provided for the full-fiber-based super-flexible thermoelectric self-power-
