▎ 摘　　要

NOVELTY - Heat conducting polymer composite material, is claimed. The material is prepared by: preparing crystalline polymer material and 0-40 wt.%, preferably 1-25 wt.% heat conducting filler into a material with a shish-kebab crystal structure, and heat compressing resulting material along the kebab direction. USE - Used as heat conducting polymer composite material. ADVANTAGE - The composite material has high mechanical properties and high bidirectional heat conductivity, which are greatly improved compared with common blending systems. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing the composite material; and (2) a method for simultaneously increasing the thermal conductivity in the orientation direction and the heat conductivity in the vertical direction of a crystalline polymer, comprising preparing the crystalline polymer material into a material with a shish-kebab crystal structure, and heat compressing obtained material along the kebab direction.
