|1. (WO2018143189) THERMAL INTERFACE MATERIAL, INTERFACE THERMAL COUPLING METHOD, AND PRODUCTION METHOD FOR THERMAL INTERFACE MATERIAL|
|Title:||THERMAL INTERFACE MATERIAL, INTERFACE THERMAL COUPLING METHOD, AND PRODUCTION METHOD FOR THERMAL INTERFACE MATERIAL|
The present invention achieves: a graphite-based thermal interface material that exhibits excellent thermal resistance properties even when used between members having uneven surfaces; and a production method for such a thermal interface material. This thermal interface material comprises a flexible or fluid substance (A) and a graphite film (B), wherein the graphite film has a thickness falling within the range of 100 nm to 15 μm, a density falling within the range of 1.20-2.26 g/cm3, and a thermal conductivity in the film surface direction of at least 500 W/mK, and the weight ratio (A/B) between (A) and (B) falls within the range of 0.08-25.
