NOVELTY - Ionic liquid gel composite fiber with high thermal voltage has a fiber substrate and an ionic liquid gel coating compounded on the surface of the fiber substrate. The thickness of the ionic liquid gel coating is 5-100 µm. The ionic liquid gel coating comprises 50-90 wt.% an ionic liquid, 7-47 wt.% an organic polymer and 3-30 wt.% an inorganic nano-filler. USE - Ionic liquid gel composite fiber with high thermal voltage useful in the field of wearable thermoelectric materials. ADVANTAGE - The method controls the components, the structure and the coating thickness of the ionic liquid gel, so that the prepared ionic liquid gel composite fiber has both thermoelectric property and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the ionic liquid gel composite fiber with high thermal voltage, which involves: (S1) carrying out surface modification on isotropic or anisotropic inorganic nano-filler by adopting a surfactant to obtain modified inorganic nano-filler; (S2) dissolving 5-20% organic polymer in a solvent, adding the modified inorganic nano filler and the ionic liquid, blending, fully stirring and dispersing to obtain an ionic liquid gel solution; (S3) soaking the pretreated fiber base material in the ionic liquid gel solution to enable the ionic liquid gel to form a uniform coating on the surface of the fiber base material; and (S4) repeatedly soaking and drying
