Preparation and Study of PMMA/TiO2 Nanocomposites

The PMMA/TiO2 nanocomposites were prepared by in situ polymerization，the dissolution, thermal stability and the mechanical property of the nanocomposites were studied. The results indicated that nano-TiO2 may be crosslinking points in the matrix and the thermal stability of the nanocomposites became higher. As the content of nano-TiO2 increased, the mechanical properties of the nanocomposites had great changes.
