Preparation, Characterization And Property Studys Of Polycarbonate Montmorillonite And Polyethylene Terephthalate/Montmorillonite Nanocomposites

Silyation montmorillonites were prepared by reaction of montmorillonite with three kinds of silane coupling agents and the reaction mechanism was discussed through X-ray powder diffraction (XRD) and chromphoric reaction of salicylalcohol with amido group of silane coupling agents. It was found that Active hydroxyls distribute on the edge of montmorillonite and silylation reaction of montmorillonite with coupling agents is more preferential than self-polymerization of coupling agents. Polystyrene quarternary ammonium salt (COPSB) was synthesized. The organo-montmorillonite modified simultaneously with 3-aminopropyl triethoxysilane and COPSB was prepared and characterized by IR, Element analysis, TGA and XRD. Intercalated structures and some possible exfoliated structures of the...
