石墨烯改性PDC-SiCNO陶瓷的制备及其介电性能
Preparation of graphite modified PDC-SiCNO ceramics and its dielectric properties
摘要
Abstract
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 used to study the effect of SiCNO-GO ceramics on the dielectric properties. The results show that the microsphere density and particle size of SiCNO-GO ceramics are related to the content of GO. With the increase of GO content in SiCNO-GO ceramics, the dielectric constant and dielectric loss of SiCNO-GO ceramics also increase, reach the maximum value when the GO mass fraction is 0.1%. When the GO mass fraction is 0.3%, the dielectric constant and dielectric loss of the SiCNO-GO ceramics decrease.关键词
