三维（3D）导电网络的构造是在低填料含量下实现硅橡胶的高导电性和导热性的有效途径。本文通过在基体中构建二维-三维协同网络结构，制备了高性能硅橡胶复合材料。结果表明，鳞片石墨（FG）、导电海绵（CS）和硅橡胶之间存在较强的界面相互作用。随着FG和CS的加入，硅橡胶复合材料的热导率和电导率分别提高了0.51 W/m·K和52 S/m，比纯硅橡胶分别提高了320%和13个数量级。硅橡胶复合材料也显示出良好的热稳定性和力学性能。因此，这项研究为实现高性能硅橡胶提供了一个新的范例。
The construction of a three-dimensional (3D) conductive network is a potent approach to achieving high electrical and thermal conductivity of silicone rubber at low filler content. In this work, silicone rubber composites with high performance were prepared by constructing a 2D-3D collaborative network structure in a matrix. The results indicate that there is a strong interfacial interaction between flake graphites (FGs), conductive sponges (CSs), and silicone rubber. With the addition of FG and CS, the thermal and electrical conductivities of silicone rubber composites increase of 0.51 W/m·K and 52 S/m, which were 320% and 13 orders of magnitude higher than that of pure silicone rubber, respectively. The silicone rubber composites also display good thermal stability and mechanical properties. Hence, this research provides a new paradigm for achieving high-performance silicone rubber.
