Problems solved by technology

However, the synthesis method is very cumbersome, and organic-inorganic hybrid materials have very high requirements for the compatibility of the two phases.
At the same time, with the development of electronic equipment, electronic materials, especially thin film materials, are required to develop in the direction of ultra-thin. At present, plate-shaped heat-conducting materials for electronic equipment cannot meet the needs of industrialization.

Description

Technical field [0001] The invention belongs to the technical field of electronic materials, and specifically relates to a thermally conductive plate-shaped material for electronic equipment and a preparation method thereof. Background technique [0002] Thermal conductive materials are widely used in the field of electronic equipment, especially plate-shaped materials, which are widely used in electronic heat exchange devices and electronic information engineering devices. For a long time, metal materials have been widely used as heat-conducting materials, but metals are relatively expensive and are not resistant to chemicals, limiting their applications. Researchers applied functional coatings on metal surfaces to improve the corrosion resistance of metal thermal conductive materials, but greatly reduced thermal conductivity. Composite materials are important basic materials for high-tech fields such as information technology, biotechnology, energy technology, and national def...
