Abstract

The invention provides a high polymer composite material, which is formed by fully blending a thermal conduction material (such as graphene), with an electromagnetic wave shielding material with EMI shielding efficacy and a high polymer binder. Thus, the thermal conductivity coefficient and the shielding efficiency of the overall composite material are enhanced, so that the provided composite material can be ensured to have thermal energy dissipated by a heat producing source and can effectively shelter electromagnetic wave interference.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a polymer composite material capable of absorbing electromagnetic waves, shielding electromagnetic wave interference, and high thermal conductivity. Background technique [0002] In recent years, electronic components such as CPUs, MPUs, and LSIs, which are installed inside personal computers and mobile phones, are all oriented towards high-density and high-integration designs. As a result, due to the increase in precision, electromagnetic waves are scattered inside electronic products, resulting in internal electromagnetic wave disturbances. Interference problem; with CPU, MPU, LSI and other electronic components operating under high-performance, high-transmission, and high-efficiency conditions, resulting in increased heat generation, if the waste heat generated during operation cannot be efficiently removed, the temperature between electronic components A large increase will cau...
