Silicon carbide (SiC) is widely used to improve the non-linear conductivity of resistive field grading composite. In this paper, SiC nanoparticles are modified into core-shell with silica (SiO2) coating on surface and characterised by transmission electron microscopy X-ray diffraction, respectively. The 7 wt% [email protected]2/epoxy nanocomposite then prepared, pure epoxy SiC/epoxy prepared as...
