英文摘要Microcellular polystyrene/LCP in situ composites with cell diameter less than 4 mum are prepared by using pressure quenching after supercritical CO2 saturating at 25 MPa, 80 degreesC for 6 h. Characterization of the microcellular structure of these blends is conducted to reveal the influence of LCP addition, LCP ratio and compatibilizer on the microcellular blends. The typical structure of these microcellular PS/LCP blends is that the microvoids only exist in the polystyrene phase. This structure results from the poor adsorption of supercritical CO2 by LCP under the experimental conditions. The cell diameter of the microcellular blends is smaller than that of microcellular PS. An increase of cell size is also found from skin to core in microcellular blends. The microcellular blends with ZnSPS has larger cell size than those without ZnSPS, which is the consequence of the improvement of interfacial adhesion. It is because CO2 could easily diffuse, out through the gap between poor adhesion interface of blends without ZnSps.
