Effects of nanoclay addition on phase morphology and stability of polycarbonate/styrene-acrylonitrile blends
Source abstract
Abstract
Abstract In this work, an extensive study was performed on the compatibility and morphological stability of polycarbonate/styrene-acrylonitrile (PC/SAN) blends and on the effects of nanoclay addition to these systems. PC/SAN blends of different compositions were prepared by melt extrusion and their morphologies were characterized as prepared and after annealing at high temperature to evaluate their morphological stability. The effects of nanoclay with different organic modifiers and acrylonitrile (AN) content in the SAN copolymer on the morphology of the PC/SAN blends were also evaluated. The results indicate that the nanoclay reduces the domain size of SAN phase and stabilizes the system morphology even without complete exfoliation. Organoclays particles with polar organic modifiers were preferably located inside the SAN domains, while in blends containing organoclays with nonpolar modifiers, the clay particles migrated to the interface, resulting in domain reduction and improved morphological stability.
