▎ 摘　　要

NOVELTY - Thermal interface material comprises a thermally conductive filler and a polymer matrix, where the thermally conductive filler is strip-shaped and/or fibrous, and the width of the strip-shaped thermally conductive filler is 1-50 mm, and the thickness is 0.05-5 mm, and the width of the fibrous thermally conductive filler is 0.01-1 mm, and the thickness is 0.001-1 mm, and the thermal conductive fillers are arranged parallel to each other and run through the thickness direction of the thermal interface material. USE - Thermal interface material. ADVANTAGE - The material is soft, and has high thermal conductivity, low interface thermal resistance, compression resistance, excellent elasticity, effective filling of tolerances, and extremely low application thermal resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing the thermal interface material, involving (a) providing the thermally conductive film, thermally conductive sheet or thermally conductive plate, (b) cutting the thermally conductive film, thermally conductive sheet or thermally conductive plate into strip-shaped thermally conductive fillers and/or fibrous thermally conductive fillers, (c) combing the strip-shaped thermally conductive filler and/or fibrous thermally conductive filler to be arranged in parallel in one direction to form a filler array structure, and pouring a polymer matrix into the filler array structure to obtain a thermally conductive filler-polymer composite material, and (d) cutting the thermally conductive filler-polymer composite material with a plane perpendicular to the orientation direction of the strip-shaped thermally conductive filler and/or the fibrous thermally conductive filler as a cutting plane to obtain the thermal interface material.
