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.
