Study On Polymer/Mesoporous Molecular Sieve In-Situ Polymerized Composites

In this thesis, the PET/molecular sieve composite and PMMA/molecular sieve composite were prepared by the in-situ polymerization. Some characterization method such as DSC, TG, FTIR, XRD and SEM etc were used to observe its structures and properties.Usually there are large specific surface (more than 700m~2/g) and large pore capacity (more than 0.7cm~3/g) in the mesoporous molecular sieve, It was widely used in the catalysts, The mesoporous molecular sieve could also absorb some kinds of monomer and under certain condition the polymerization could happen in the pore. The polymer chains formed in the pore could entangle with the polymer chains in the matrix and the polymer chains in the pore could form network which could interweave with the molecular sieve's network, Therefore the interaction between the matrix and the molecular sieve could be improved. Also the molecular sieve could use as nucleating agent, which could enhance the crystallized property of...
