Nanotechnology has attracted the interest of many scientists because changes in physical properties occurred at size 1-100 nm form vast surface area, high mechanical strength, and porosity. Silica is an element with uses various fields such as biotechnology. nanoparticles are silica made on a nanoscale whose use increasing. Nanosilica widely used industry retention drainage aid, usually associa...

Nanosilica dispersion was added to waterborne polyurethane by using three different physical mixing procedures differing in the flow regime (tangential, laminar, radial) and stirring rate (300–2400 rpm). The influence of procedure on structural, thermal, rheological, mechanical, surface adhesion properties polyurethanes (PUs) containing 1 wt% nanosilica evaluated. functionalized with acrylic mo...

In the current work, experimentations have been accomplished to assess impact of diffusing nanosilica particles in epoxy matrix on mechanical and thermal performance luffa fibre reinforced composite material. The composition are fixed as 80 : 20 throughout study, is disbanded diversified volume fractions 0%, 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, respectively, while preparing luffa/epoxy/nanosilica (LES...

the preparation and characterization of the vinyltriethoxysilane-modified silica nanoparticles were investigated. also the surface tension of polystyrene, native (hydrophilic) silica and silane-modified (hydrophobic) silica were determined. two kinds of polystyrene/silica (treated and non-treated) nanocomposites were prepared with different filler loadings by solution method. their viscoelastic...
