碩士 === 義守大學 === 電子工程學系碩士班 === 98 === The capacitors were fabricated on flexible substrates by using spin coating process various ratio of high dielectric constant ceramic materials were mixed with low dielectric constant resins by a triple roller. The effect of high permittivity materials on the dielectric properties were investigated. In addition, conductive materials were added in to the matrix to increase dielectric constant of composites. Dielectric properties of the composite depend on the amount of high permittivity ceramics and higher amount of ceramics result in higher dielectric constant. The dielectric constant of 25wt% al added 50wt% BaTiO3+50 wt%ITK5517 specimen is 127 measured at 1kHz and dissipation factor is 0.05. The addition of conductive Al particles greatly enhance dielectric constant of the composites.
