Abstract
In order to study the effect of the TiO2 particle crystalline composition (with different proportions of rutile and anatase crystals) on the dielectric properties of the composite, titanium dioxide (TiO2) particles and TiO2/poly(vinylidene fluoride-co-trifluoroethylene) [P(VDF-TrFE)] composites were synthesized by a reflux method and the solution route, respectively. The results indicated that the optimum TiO2 particle crystalline composition is anatase content of 37% and rutile content of 63% for dielectric-constant modifier applications. Furthermore, a dielectric constant of 25.7 with dielectric loss of 0.17 at 100 Hz at room temperature were obtained in the composite with 40 wt% TiO2 particles. (© 2012 WILEY-VCH Verlag GmbH & Co.
