Transparent PMMA/ZrO 2 nanocomposites were prepared by in-situ bulk polymerization of methyl methacrylate (MMA)/ZrO 2 dispersions that were firstly synthesized using nonaqueous synthesized ZrO 2 nanocrystals and the function monomer, 2-hydroxyethyl methacrylate (HEMA), as the ligand. The dispersion behavior of ZrO 2 nanoparticles in MMA, structure, mechanical and thermal...
Poly(methyl methacrylate)/zirconia (PMMA/ZrO 2 ) nanocomposites with ZrO 2 content as high as 15wt% were prepared by modifying non-aqueous synthesized ZrO 2 nanoparticles with methacryloxypropyltrimethoxysilane (MPS) in tetrahydrofuran, dispersing MPS-functionalized ZrO 2 nanoparticles in MMA and following in situ bulk polymerization with controlled pre-polymerization...
Polyester polyol/titania hybrid resins and their corresponding polyurethane/titania hybrid films were prepared by in situ method via sol–gel process of titanium n-butoxide under acidic condition. The effects of the contents and types of titania sol on the microstructure and some mechanical and optical properties of the hybrids were investigated. It was found that introducing titania into the resin...
Homogeneous organic–inorganic hybrid materials with high performance were successfully prepared by mixing (3-methacryloxypropyl)trimethoxysilane (MPMS) capped acrylic resin with titania synthesized by sol–gel approaches. The effects of the titania content, the amount of water and nature of catalysts in the sol–gel as well as the ratios of mixed solvents of butyl acetate and ethanol on the structures...
Acrylic resin/titania organic-inorganic hybrid materials were prepared by the two approaches. One approach (BL method) was blending titania produced by the sol-gel process with synthesized acrylic resins containing various content of acrylic acid (AA). Another approach (IS method) was the in situ polymerization of acrylic monomers in synthesized titania sols. The structure and mechanical, thermal...
