用超临界CO2制备聚合物共混物及其性能研究

Supercritical Fluids have many unique properties. Scupercritical (SC).technology opens up a new way for the development of material science..In this project, using SC CO2 as a solvent for monomers and initiators, we.prepared PP/PS、 SR/PP composites，grafting composite of PA onto PP,.PP/PS composite with interpenetrating network structure, and MCM-41/PA composite. The dependence of composition, phase size,microstructure and morphology, physical and mechanical properties on pressure of CO2, properties of polymer substrates and monomers have been studied.
