Structure–property relationships in hybrid dental nanocomposite resins containing monofunctional and multifunctional polyhedral oligomeric silsesquioxanes
Organic-inorganic hybrid materials, such as polyhedral oligomeric silsesquioxanes (POSS), have the potential to improve the mechanical properties of the methacrylate-based composites and resins used in dentistry. In this article, nanocomposites of methacryl isobutyl POSS (MI-POSS [bears only one methacrylate functional group]) and methacryl POSS (MA-POSS [bears eight methacrylate functional gro...
متن کاملRemoval of methylene blue using polyacrylic acid/ octavinyl polyhedral oligomeric silsesquioxane nanocomposite
Polyacrylic acid/ octavinyl polyhedral oligomeric silsesquioxane, nanocomposite hydrogel with 3-D network was synthesized via radical polymerization. Octavinyl polyhedral oligomeric silsesquioxane was used as crosslinker and nanofiller simultaneously in the preparation of the hydrogel. Hydrogel adsorption performance was determined by adsorption of methylene blue. The adsorption capacity was ev...
متن کاملThermodynamic and transport properties of polyhedral oligomeric sislesquioxanes in poly(dimethylsiloxane).
Polyhedral oligomeric silsesquioxane (POSS) molecules when functionalized appropriately and dispersed in polymers show promise as monodisperse organic-inorganic hybrid nanocomposite materials characterized by superior mechanical properties. We report here molecular-simulation results for POSS-POSS radial distribution functions, potentials of mean force, and self-diffusion coefficients for POSS ...
متن کاملSynthesis and Gas Transport Properties of Graphene Oxide Membranes
Graphene oxide (GO) membranes have shown promising gas separation characteristics that make them of interest for large-scale industrial applications. However, the gas transport mechanism for GO membranes is unclear due to inconsistent permeation and separation results reported in literature. GO membranes examined for gas separation were prepared on substrates and/or by synthesis methods that ar...
متن کاملPhysical Properties of Polyhedral Oligomeric Silsesquioxanes–Cycloolefin Copolymer Nanocomposites
Properties of cycloolefin copolymer (COC)– polyhedral oligomeric silsesquioxanes (POSS) nanocomposites, prepared by melt compounding, have been investigated. Composites retained the optical transparency of the matrix up to a nanofiller content of 5 wt %. whereas for higher percentages the formation of a crystalline phase, due to the presence of agglomerated nanoparticles, was revealed by X-Ray ...
