摘要: Interphases in polymer nanocomposites play an important role. Understanding them is the key to developing efficiently designed with tailored properties. The aim of this study investigate effect nanoparticle volume and interphase between core shell on dielectric properties, further understand characteristics surface polymer. For purpose, five types nanoparticles were synthesized $SiO_{2}/SiO_{2}$, $TiO{2}/SiO{2}$, $TiO{2}$, SiO 2 hollow silica (h - ) epoxy nanocomposite samples prepared. To confirm successful synthesis nanoparticles, FTIR spectra TEM images are presented. Further, these characterized by spectroscopy (0.1 Hz 1 MHz). Core-shell showed significantly lower permittivity than composites conventional, h-SiO having lowest permittivity. A typical $\beta$ relaxation also observed its correlation degree crosslinking discussed. , additional peak at frequencies observed. origin postulated be either absorbed water or $\alpha$ – relaxation.
