Abstract

Three hybrid nanomaterials (MST, VST and GST) based on (3-methacryloxypropyl)-silsesquioxane (MS), Vinyl-silsesquioxane (VS), (3-glycidoxypropyl)-silsesquioxane (GS) and modified with tetraethoxysilicate (TEOS) were prepared using hydrolytic condensation. The dielectric constant (epsiv_r) testing profiles of MST, VST and GST with 0, 5, 10, 15, 20 and 25 wt-% TEOS can be divided into three frequency ranges (0.10-21.54, 21.54-100.00 and 100.00-1000.00 KHz). MST has the lowest epsiv_r due to the larger-sized methacryloxy groups and GST has the highest epsiv_r due to the ring-opening of the epoxy groups. The influence of the TEOS fractions of MST, GST and VST on the epsiv_r values and surface morphology was also analyzed.
