Although polycarbonate has been widely used in many technical applications, there exist many potential applications for which an enhancement of PC properties is necessary. To improve the mechanical properties, the use of inorganic fillers is an excellent way. In this study, ally-mica coated with functional group such as epoxy and amino was filled in to polycarbonate at loadings between 5% and 20% by large scale extruder. To improve dispersion characteristic in PC-mica system, dispersive agent was also added. The loading of dispersive agent is between 0% and 10%. The morphologies of the materials were investigated to confirm the dispersion characteristic and the interfacial characteristics between PC matrix and alloy-mica. In addition, the mechanical characteristics of the PC/mica composites, which depended on the mica and dispersive agent contents were evaluated using mechanical test such as impact, tensile and flexural test. |
