TL;DR: The SiO(2)/polystyrene nanocomposite particles were synthesized through miniemulsion polymerization by using sodium lauryl sulfate surfactant, hexadecane costabilizer in the presence of silica particles coated with methacryloxy(propyl)trimethoxysilane.

TL;DR: In this paper, nanosilica particles were directly introduced into polyester polyol resins through in situ polymerization and blending methods, then cured by isophorone diisocyanate (IPDI) trimers to obtain nanocomposite polyurethanes FTIR and TGA analyses indicated that more polyester segments had reacted with silica particles during in situ polyol polymerization than during the blending method, accompanied by higher tensile properties, macrohardness, abrasion resistance, and UV absorbance.

TL;DR: In this article, four kinds of colloidal silica particles with different size (27, 58, 79 and 173 nm, respectively) were synthesized by sol-gel process and modified with 3-glycidoxypropyltrimethoxysilicane, then homogenously dispersed into the epoxy resin and cured with alicyclic amine on aluminum alloy substrates.

TL;DR: A series of silica particles with different size and surface groups were prepared through the sol-gel process of tetraethylorthosilicate, then directly introduced into polyester polyol resins via in situ (IS) polymerization or blending (BL) method and investigated by Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), viscosity measurement, particle size analyzer and transmittance electron microscope (TEM).

TL;DR: In this article, a stable PS/SiO 2 core-shell hybrid colloid was proposed, which was first synthesized via surfactant-free emulsion polymerization of styrene by using a cationic initiator, and the hydrolysis and condensation of tetraethoxysilane (TEOS) was then carried out in acidic aqueous ethanol medium in the presence of PS colloids.
