Title:
GECKO-CLAW-IMITATING COMPOSITE THERMAL INTERFACE MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/036611
Kind Code:
A1
Abstract:
Disclosed in the present invention are a gecko-claw-imitating composite thermal interface material and a preparation method therefor. The method comprises the following steps: (1) preparing a polymer-based thermal interface material prepolymer on a template having a micron-scale array structure on the surface, and demolding same to obtain a polymer-based thermal interface material prepolymer having a micron-scale array structure on the surface; and (2) implanting carbon nanotubes into the micron-scale array structure of the polymer-based thermal interface material prepolymer obtained in step (1) by means of an electrostatic flocking method, and curing same to obtain a gecko-claw-imitating composite thermal interface material. In the present invention, by means of treating the surface structure of a thermal interface material, a micro-nano two-level gecko-claw-imitating structure is formed, such that an interface contact area is effectively increased, an interface adsorption force is enhanced, and interfacial thermal contact resistance is reduced.
