Problems solved by technology

Each layer of hexagonal BN is a planar hexagonal ring structure with B atoms and N atoms arranged alternately, and B atoms and N atoms are bonded together by SP2 hybrid covalent bonds, and the layers are bonded by Van der Waals force. Therefore, the structure of each layer of hexagonal BN is stable, but the layers are easy to peel off

Description

technical field [0001] The invention relates to the technical field of heat-conducting materials, in particular to an antistatic epoxy heat-conducting material and a preparation method thereof. Background technique [0002] As a functional material with great application prospects, high thermal conductivity polymer-based composite materials play a very important role in many manufacturing and high-tech fields such as microelectronics, aviation, aerospace, military equipment, electrical appliances, etc. important role. Especially in recent years, with the rapid development of electronic integration technology, the assembly density has increased rapidly, the volume of electronic components and logic circuits has been reduced by tens of thousands of times, and electronic instruments and equipment have become increasingly ultra-light, thin, short, and small. Under high-frequency operating frequency, the working thermal environment of semiconductors moves rapidly towards high te...
