Herein we report the development of Ca0.8 Sm0.133 TiO3/ Poly butadiene composites as an ideal candidate for the fabrication of microwave dielectric substrates. Because of their exceptionally high dielectric constant and low tan ?, ceramic materials have been extensively investigated for high-frequency applications, particularly in the microwave region. Phase Pure Ca0.8Sm0.133TiO3 was developed using a Standard solid-state approach. The matrix consist of Poly Butadiene (PB) powder is consistently blended with the filler by using a two-roll mixer. The thermo-lamination process is used to create filler polymer composites. The optimum filler-loaded composite with a Coefficient of Thermal Expansion of 35 has a dielectric constant of 9.2 and a tan ? of 0.003. The thermal expansion of the substrates was found to be very similar to that of copper, allowing for superior copper cladding adaptation and the development of a flexible microwave substrate material. |
