Morphology and mechanical properties of bisphenol A polycarbonate/poly (styrene-co-acrylonitrile) blends based clay nanocomposites

Abstract

Two organic modified clays (Cloisite®30B (CL30B) and PCL /Cloisite®30B masterbatch (MB30B)) were used to improve the mechanical properties of polycarbonate (PC)/poly (styrene-co-acrylonitrile) (SAN) blends. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) measurements of the melt blended nanocomposites revealed that partially exfoliated and partially degraded structure was obtained and the clay platelets were located mostly in the SAN phase and at the two-phase boundary. Dispersion of the clay platelets is better when MB30B were used. The mechanical properties of the clays filled nanocomposites vary accordingly and when MB30B is used better mechanical properties can be achieved. Tensile strength increases 41% at maximum as the CL30B loading is 5wt%, while elongation at break decreases dramatically. Impact strength can be improved up to 430% compared to the pure blend when 1wt% MB30B was used.
