AbstractMonomer styrene and initiator 2,2'-azobis(isobutyronitrile) (AIBN) dissolved in supercritical (SC) CO2 were impregnated into SC CO2-swollen polypropylene (PP) matrix at 35.0 degreesC, and the monomer were then polymerized within the PP substrates at 70 degreesC, resulting in polypropylene/polystyrene (PP/PS) composites. The Young's modulus and tensile strength of the PP were improved significantly in the presence of PS. Transmission electron microscopy (TEM), differential scanning calorimetry (DSC), and infrared spectroscopy were used to characterize the morphology and microstructure of the composites. The results showed that the PS was more homogeneously dispersed in the blends and its phase size was in the range of nanometers. Some of the PS entangles with PP in the composites. The special microstructures and morphology of the blends result in the enhanced mechanical performances of PP/PS composites.
