Description

technical field

[0001] The invention relates to the technical field of composite materials, in particular to a conductive composite material and a preparation method thereof. Background technique

[0002] In recent years, with the rapid development of electronic information technology, the market has increasingly stringent requirements on the specificity and functionality of conductive materials. Conductive materials have gradually developed from single materials such as metals to conductive composite materials.

[0003] In the prior art, conductive composite materials mostly use conductive media and low-conductivity or insulating substrates through blending, adsorption or coating to obtain composite conductive materials with different conductivity. Common conductive media are silver powder, copper powder, etc., and common low-conductivity or insulating substrates are polymer materials such as epoxy resin and acrylic acid.

[0004] The inventors found that since the above-...
