Research on $ Ba_{2} $$ Ti_{9} $$ O_{20} $-filled polybutadiene composites with near-zero temperature coefficient of dielectric constant by $ SiO_{2} $ addition
Abstract A study on $ Ba_{2} $$ Ti_{9} $$ O_{20} $ and $ SiO_{2} $ ceramic powder-filled polybutadiene (PB) composite substrates was conducted in this paper. The total content of ceramic fillers was a fixed value of 85 wt.% and the $ SiO_{2} $ content varied from 5 to 25 wt.%. The analyses of FTIR,...

| 520 | |a Abstract A study on $ Ba_{2} $$ Ti_{9} $$ O_{20} $ and $ SiO_{2} $ ceramic powder-filled polybutadiene (PB) composite substrates was conducted in this paper. The total content of ceramic fillers was a fixed value of 85 wt.% and the $ SiO_{2} $ content varied from 5 to 25 wt.%. The analyses of FTIR, XPS, TEM, Contact Angle testing, and SEM were performed to study the surface characteristics of Vinyltrimethoxysilane (A171)-modified $ Ba_{2} $$ Ti_{9} $$ O_{20} $. The microstructure of composite substrates displayed that $ Ba_{2} $$ Ti_{9} $$ O_{20} $ and $ SiO_{2} $ ceramic fillers distributed in PB homogeneously with a small amount of $ SiO_{2} $ addition. However, $ SiO_{2} $ filler particles agglomerated and poorly dispersed in composites with 25 wt.% $ SiO_{2} $ loading. Furthermore, the effects of $ SiO_{2} $ filler loading on density, porosity, dielectric properties, and mechanical properties of composites were investigated in detail. Last, the composites exhibited medium dielectric constant $$(\varepsilon_{r} = 7.32),$$ low dielectric loss $${\text{(tan }}\delta { = 0}{\text{.002),}}$$ near-zero temperature coefficient of dielectric constant ($$\tau_{\varepsilon } = - \,8.07 {\text{ppm}}/^\circ {\text{C}}$$) at a high frequency of 10 GHz, relatively low porosity (1.36%), and acceptable bending strength (75.26 MPa) at 65 wt.% $ Ba_{2} $$ Ti_{9} $$ O_{20} $ and 20 wt.% $ SiO_{2} $ fillers loading. | ||
