NOVELTY - Preparation of anisotropic high heat-conducting flexible material involves: (1) adding a sheet-shaped heat-conducting filler to a polymer material solution to obtain a mixed solution; (2) dripping the mixed solution on a saturated sodium sulfate aqueous solution for salting out, and obtaining a film-shaped composite material after salting out; and (3) clamping the film-shaped composite material using a flat plate, pressurizing, and drying in an oven. USE - Preparation of anisotropic high heat-conducting flexible material (claimed) used for electronic device. ADVANTAGE - The method is simple, feasible, and suitable for mass production, and provides anisotropic high heat-conducting flexible material, which can promote the rapid development of flexible electronic packaging heat dissipation material. The mechanical properties of the polymer material are preserved to the greatest extent because the filling amount of the filler is low.
