Porosity control of alkali-activated aluminosilicates via functional alkoxysilane additives
Geopolymers were synthesized with alkoxysilane and other organo-silane supplements to improve adhesion to organic polymers and to modify porosity. Uncured geopolymer slurry was found to be miscible with various alkoxysilanes, and the resulting cured geopolymer strongly adhered to organic polymers …

Hybrid Inorganic-Organic Materials: Novel Poly(Propylene Oxide) Based Ceramers, Abrasion Resistant Sol-Gel Coatings for Metals, and Epoxy-Clay Nanocomposites. With an Additional Chapter On: Metallocene Catalyzed Linear Polyethylene
… Unique ceramers were prepared based on an alkoxysilane functionalized soft organic oligomer, poly(propylene oxide) (PPO), and tetramethoxysilane (TMOS). Despite the formation of covalent bonds between the inorganic and organic constituents, the resulting network materials were phase …

Silica Dispersion for Applications in Rubber Processing
… by coupling agents (CA) such as bi-functional alkoxysilane molecules. The CA chemically binds to surface silanol groups so that interparticle and particle-polymer interactions are modified in a manner that improves the silica dispersion quality as well as the processability of silica-reinforced …

Novel Fluorous Hybrid Surface Modification Characterized by Wetting Dynamics, Morphology and Nanomechanics
… and triethoxysilyl chain ends and (b) an alkoxysilane that together with BB chain ends comprise precursors to a “nanoglass”, NG phase. This paper focuses on the extent of modification for a conventional aliphatic polyurethane using a range of fluoropolyoxetane …

A DIGITAL DATA ACQUISITION SYSTEM FOR INELASTIC ELECTRON TUNNELLING SPECTROSCOPY
… Oi-cyanoacrylate adhesives (CH2C(CN)COOR) (ii) alkoxysilane coupling agents (RSi(OR’)3) on aluminium oxide. High-quality tunnel spectra are presented and assigned. Evidence suggests that a-cyanoacrylates adsorb through formation of carbonyl - surface hydroxyl hydrogen bonds, conventional …

Inorganic-Organic Sol-Gel Derived Hybrid Materials as Abrasion Resistant Coatings
… system of an alkyltriethoxysilane (T) and a tetraalkoxysilane (Q). At pH 0-2 and pH 4-5, the relative condensation reactivities of the T and Q species in this system were compared using 29Si NMR spectroscopy. After thermal curing, 13C or 29Si solid state NMR spectroscopy was used to estimate the …
