The Preparation of Flexible Substrate using BaTiO_3/Polymer Composites for Application in High Frequency Devices

摘要

BaTiO_3 has good dielectric properties and is widely used in ceramic capacitors, thermistors, etc. In this study, BaTiO_3 ceramics prepared by sol-gel powder, then mixed in the organic polymer polyether imide and dispersant (surface active agents) and silane coupling agent (silane coupling agent) of the composite material on flexible substrates, And analysis of its properties and electrical properties. Increase by a ceramic powder, to explore the impact of the substrate. In the physical analysis is used XRD, SEM to measure the intensity of crystalline phase and surface uniformity of the electrical measurement using HP4294 measuring dielectric constant and dielectric loss.
