Abstract
In this study calcium copper titanate CaCu3Ti4O12 CCTO was used as filler in epoxy composite using different mixing and fabrication methods to investigate their suitability as dielectric materials for embedded capacitor Results show that 20 vol CCTO/epoxy composite produced using ultrasonic mixing method yield slightly higher dielectric constant T 5 and T onset as compared to 20 vol CCTO/epoxy composite produced using agate mortar method Meanwhile sample with 20 vol CCTO/epoxy composite fabricated using spin coating method shows slightly higher dielectric constant T 5 T onset and E′ and lower CTE value compared to 20 vol CCTO/epoxy composite fabricated using hot press method Nevertheless 40 vol CCTO/epoxy composite fabricated using hot press method shows the highest dielectric constant T 5 T onset and E′ and lowest CTE value compared to all composites In short composite produced using ultrasonic as mixing method and spin coating as fabrication method are suitable to be utilized to produce epoxy composite as dielectric materials for embedded capacitor applications
