In order to improve some properties of PS, some additives can be used and production of blends and composites are common as well. These methods, due to the shorter time needed than developing a new material, are preferred. Silicon carbide (SiC) is a semiconductor material with high oxidation resistance and with high thermal conductivity. In this study, SiC nanoparticles, which are not compatible with PS, are coated with PS to render it compatible and by using these nanoparticles, PS nanocomposited having SiC have been prepared with molten mixing method. For this reason, SiC nanoparticles were first coated with PS. To prevent the agglomeration fo SiC nanoparticles in PS, the coated SiC nanoparticles (PS/SiC) were prepared followed by determination of coating percentage. This characterization was performed with analysis and TGA. Coated SiC particles were added into the extruder without the need of external addition of a compatibilizer and the homogeneity of the molecular distribution was examined. PS was added 4% PS/SiC, extruder outputs were collected and pressed into pellets and films were produced with hot press from these pellets. Similar experiments were performed with SiC particles which were not coated. Thermal, morphologic and mechanical properties of unadultareted PS, composite having 4% PS/SiC, and a sample of PS with 4% uncoated SiC were investigated. These samples revealed that TGA, microscopy and DMA analyses yielded better distribution in PS-coated SiC, along with the observation of better mechanic strength and thermal behavior, and a homogeneous microscopic appearance. }, number={1}, publisher={Turkish Chemical Society}
