“…Due to its unique particle surface characteristic, nano SiO 2 is easy to form net-like structure with polymer or monomer and closely bond with matrix interface, which can enhance physicochemical properties. The addition of even a small quantity of SiO 2 will make the matrix have better mechanical, optical and thermal properties than traditional composite materials (Chen et al 2008).…”

Nanocomposite dental resins composed of polyhedral oligomeric silsesquioxane nanocomposite matrix and 0, 0.5,1, 1.5 and 2 wt% nano SiO 2 as filler were prepared by light curing method. The nanocomposite resins were characterized by performing compressive, three-point flexure, nanoindentation and nanoscratch testings as well as optical microscopy and scanning electron microscope analysis. The effects of different nano SiO 2 contents were studied on compressive strength, flexural strength, hardness and resistance of composite resin. From the mechanical results, it was found that nano SiO 2 effectively enhanced the mechanical properties of the composite resins at low content. With the increase of the nano SiO 2 content, the mechanical properties decreased. It was attributed to the content of nano SiO 2 and dispersion of nanoparticles in matrix.

“…Compared to the mechanical dispersing technique for silica‐based nanoparticles, the sol–gel technique is a very efficient chemical method for embedding agglomerate‐free silica particles in epoxy resins [17]. However, only few studies [18–20] have been done on the preparation and characterization of epoxy composites incorporated with submicron‐sized silica spheres (100 nm –1 μm). In this study, submicron‐sized silica spheres were prepared by the sol–gel reaction from tetraethyl orthosilicate (TEOS) in a basic environment and their surfaces were further modified with 3‐methacryloxypropyl trimethoxy silane (MPTMS).…”

To investigate the interfacial effect on properties of epoxyacrylate-silica composites, submicron-sized silica spheres were synthesized by sol-gel reaction under a basic environment and their surfaces were endowed with vinyl functional groups by further modification with 3-methacryloxypropyl trimethoxy silane. The pure silica (PS) and the modified silica (MPS) spheres were characterized by Fourier transform infrared, 29 Si-and 13 C-nuclear magnetic resonance (NMR), scanning electron microscope (SEM), and particle size analyzer. The silica spheres were then added to the presynthesized difunctional epoxyacrylate resin with one vinyl group and one epoxide group at each end, in addition to the photo-and thermo-curing agents. After cure, thermal and mechanical properties of the obtained epoxyacrylate-silica composites were measured and compared. Tensile mechanical properties including initial modulus, ultimate tensile strength, and elongation at break, as well as the fracture energy of the epoxyacrylate-silica composite were all increased by increasing the content of silica spheres. Moreover, the composites filled with MPS had stronger interfacial strength between silica sphere and matrix than those with PS and thus exhibited an additional increase of tensile mechanical properties and fracture toughness. The increase of fracture toughness was owing to the crack deflection and particle-matrix debonding as evidenced by SEM pictures on the fracture surface.
