Abstract

The invention relates to a polymer matrix composite material which contains: a base material formed by polymer material, and a reinforced material dispersed in the base material, wherein the reinforced material contains micron level metal powder and nanometer level metal powder, and the powders appears in passivation state after passivated. The volume percent of the base material is 50-90%, the volume percent of the reinforced material is 10-50%, and the volume percent is based on the overall volume. By adding the reinforced material prepared with the mixture of passivated micro level and nanometer level metal powders to the base material according to a proper volume rate, the thermal conduction property of material can be effectively promoted and the aim of maintaining the property of low dielectric losses can be achieved.

Description

technical field [0001] The invention relates to the technical field of electronic composite materials, in particular to a polymer-based composite material in which passivated metal particles with different particle sizes are doped into a polymer substrate to improve thermal conductivity. Background technique [0002] With the rapid development of microelectronics technology and printed circuit board assembly technology, coupled with the demand for light, thin, small, multi-functional and high-speed products, the components of electronic devices are bound to face problems such as small internal space and difficulty in heat dissipation, resulting in high temperature during operation of electronic devices. Elevated, so that the operating stability is not good, and even reduce the service life. Using materials with good thermal conductivity in the manufacturing process as much as possible is one of the measures to solve such technical problems. Therefore, the development of ele...
