Problems solved by technology

In these patents, although the filling of heat-conducting particles improves the thermal conductivity of TIM to a certain extent, while increasing the process cost, the more critical is the introduction of structural defects, which generate interfacial thermal resistance at the bonding interface between the matrix and heat-conducting particles. ;In addition, the thermally conductive particles will increase the possibility of TIM electrical insulation performance decline, or affect its flexibility; and the intrinsic thermal conductivity of the thermally conductive particles will not be maximized due to various factors

Description

technical field [0001] The invention relates to the technical field of elastomeric thermal interface materials, in particular to a highly thermally conductive and insulating elastomeric thermal interface material filled with web-like spider silk and a hydrogel and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of electronic technology, the performance of electronic products has been improving day by day, and the degree of miniaturization, integration, and densification has also been increasing. At the same time, the power consumption and heat generation of electronic products have also increased sharply. High temperatures can reduce the stability, reliability and lifespan of electronic equipment. The way to solve this problem is to use a thermal interface material (Thermal Interface Material, TIM) with high thermal conductivity to place between the heating electronic components and the heat sink, occupy the gap between...
