▎ 摘 要
Dielectric performance of copper calcium titanate (CCTO) was improved with the surface coating of graphene reduced from graphene oxide (GO) under high temperature. Poly(phenylene oxide) (PPO) composite exhibited higher dielectric constant of 8.60 when 30 wt% graphene-coated CCTO (g-CCTO) was added as organic filler, compared to the case for untreated CCTO of 7.08.
