چکیده انگلیسی
In this study, the core-shell structured polystyrene@SiO2 (PS@SiO2) microspheres were successfully synthesized by tetraethylorthosilicate (TEOS) hydrolysis method. The synthesized PS@SiO2 microspheres were subsequently characterized by FTIR spectroscopy, XRD, SEM, and TEM respectively. The results indicated that the particle size of PS@SiO2 microspheres is about 2 μm, and the PS microsphere is uniformly coated by amorphous SiO2 shell. PS@SiO2/cyanate ester (CE)/epoxy resin (ER) composite films were prepared with PS@SiO2 microspheres as fillers and morphology of the films was inspected by AFM. The images showed that the PS@SiO2 microspheres were well-distributed in epoxy matrix. Thermal conductivity of PS@SiO2/CE/ER composite increases 131% by adding 1.0 wt% of PS@SiO2 microspheres. The volume resistivity of composites decreased with increasing of the loading of PS@SiO2 fillers and still keeping an excellent insulating performance. In addition, the dielectric constant as well as the dielectric loss of composites increased with the increased the content of PS@SiO2 microspheres.
