NOVELTY - Stretching-induced light oriented high heat conducting material, comprises a heat-conducting filler, a carbon skeleton and a polymer substrate, where the heat-conducting filler is distributed on the polymer inside, and the three-dimensional heat conducting network structure is formed by the carbon skeleton. USE - The stretching-induced light oriented high heat-conducting material is useful in a space aircraft variable high-power radiating device. ADVANTAGE - The light oriented high heat-conducting material: has light weight, high heat conductivity, and good thermal stability. The method: is simple and efficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing stretching-induced light oriented high heat conducting material, comprising (1) blending a carbon skeleton precursor and a thermally conductive filler to obtain a mixture, stretching the mixture for 5-30 times to obtain a stretching mixture, where the thermally conductive fillers in the stretching mixture are oriented and arranged, the elongation of the carbon skeleton precursor is 1011-3200%, and the orientation of the thermally conductive filler is 85-95% within a 5, (2) drying and graphitizing the stretching mixture to obtain a mixture with a thermally conductive network, adding mixture of a polymer matrix or a polymer monomer and an initiator system to the mixture with a thermally conductive network by vacuuming, obtaining a stretch-induced lightweight oriented high thermal conductivity material.
