Rutile Titanium Dioxide

Rutile TiO2 whisker/epoxy resin composites were prepared by hot-pressing process method. The effects of different content of TiO2 whiskers on the microstructure, microwave dielectric properties and flexural strength for TiO2/epoxy resin composites were investigated. Results show that flexural strength increased firstly, which can reach the maximum value (105.53 Mpa), then decreased with the content of TiO2 whisker (v%) increase. Moreover, the dielectric constant and dielectric loss of the TiO2/epoxy resin composites increase with the increased of TiO2 whisker (v%). When the content of TiO2 whisker is 60 v%, the TiO2 whisker/epoxy resin composites exhibit a higher permittivity (εr = 10.74) and relatively low dielectric loss (tanθ= 0.021).
