Abstract
The mica fillers reinforced Polycarbonate (PC) composites were fabricated using compression molding technique. The mica surface was chemically modified using vinyltrimethoxy silane and 3–Aminopropyltriethoxy silane. The properties of treated mica PC composites were examined in terms of scanning electron microscopy, thermo gravimetric analysis, differential scanning calorimetry and rheological behavior. The modified mica was observed to disperse more uniformly than the unmodified counterpart. The tensile strength and modulus also improved with treated mica filled PC composites. Polycarbonate (PC) / mica composites were prepared by twin screw extruder at 250 °C. Rheological behavior of PC/mica composites was investigated. The PC / mica composites were characterized by parallel plate rheometer system. As increasing the mica particle size and the content, storage and loss modulus of the PC / mica composites were increased.
