Abstract: | Composites based on polysterene and hybrid core-shell nanoparticles are studied; the nanoparticle core consists of silicon
dioxide, and ethylphenylic groups (organic shell) are grafted to the core surface. It is shown that the permittivity, the
volume resistivity, the thermostimulated depolarization current spectra, and the glass transition temperature of these materials
depend on the nanofiller content and, what is more important, the nanofiller distribution over the polymer volume in the form
of particles or their aggregates. |
