Preparation of graphite modified PDC-SiCNO ceramics and its dielectric properties
Graphene ball reinforced SiCNO ceramics (SiCNO-GO) were prepared by using polyvinylsi-lazane (PVSZ) as raw material and graphene oxide (GO) as carbon source and anhydrous ethanol (ETOH) as dispersant. X-ray diffraction (XRD), Raman spectroscopy (Raman), electron spin resonance (EPR) and SEM were use...
