“…A large number of Class II hybrid materials are formed through the hydrolytic condensation of an alkoxysilane (RSi(OR′) 3 ) precursor modified with a polymerizable R group, such as epoxy, methacrylic and acrylic organofunctional species. Among the various available organic substituted trialkoxysilanes, (3-methacryloxy propyltrimethoxysilane (MPTS) has been successfully used as coupling agent between silica and poly(methyl methacrylate) (PMMA) phases prepared from the co-reaction of methyl methacrylate (MMA), tetra-alkoxysilanes such as tetraethyl orthosilicate (TEOS), and tetramethyl orthosilicate (TMOS) [16][17][18][19][20][21][22][23][24][25][26][27]. These nanocomposites are used as coatings for commercial glass lenses, to increase elastic modulus and decrease brittleness, and for micropatterning wave-guide thin channels [21].…”

Polysiloxane hybrid films were deposited on 316 L stainless steel substrates by dip-coating in a sol prepared by acid-catalyzed hydrolytic co-polycondensation of tetraethoxysilane (TEOS) and 3-methacryloxy propyltrimethoxysilane (MPTS), followed by radical polymerization of methacrylic moieties. Structural features of the polysiloxane hybrids were studied using 13 C and 29 Si nuclear magnetic resonance (NMR), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA), as a function of the TEOS/ MPTS ratio, which ranged between 0 and 2. The efficiency of corrosion protection of hybrid-coated stainless steel was investigated by X-ray photoelectron spectroscopy (XPS), potentiodynamic polarization curves and electrochemical impedance spectroscopy (EIS) after immersion of the material in acidic and neutral saline aqueous solutions. The NMR and TGA results indicated a high degree of polymerization and polycondensation (85%) for the hybrid film with a TEOS/MPTS ratio of 2, as well as elevated thermal stability of 410°C and excellent adhesion. The XPS analysis confirmed the hybridized structure of the polysiloxane network, and showed that no corrosion-induced changes had occurred on the coated steel surface after 3 weeks of immersion in 3.5% NaCl solution. Potentiodynamic polarization curves showed that the hybrid coating prepared using a TEOS/MPTS ratio of 2 yielded the best anti-corrosion performance. It acts as an efficient physical barrier, increasing the total impedance and reducing the current densities by 2 orders of magnitude, compared to the bare electrode. The impedance results obtained for the two electrolytes were discussed based on the electrical equivalent circuits used to fit the experimental data.

“…, FTIR spectra of MPTMS monomer and PMPS are shown. The spectrum of PMPS clearly reveals the peaks at 1070–1010 cm −1 region due to SiOSi bonds and the symmetrical SiOSi stretching at 815 cm −1 . The characteristic peak of CC double bond of monomer MPTMS at 1636 cm −1 disappeared at the end of ATRP.…”

In this study, novel polyethersulfone (PES) and poly(trimethoxysilyl) propyl methacrylate (PMPS) containing hybrid materials were prepared. PES was functionalized with trimethoxysilane groups by UV‐induced grafting reaction. PMPS was synthesized by atom transfer radical polymerization. In the followed process, the functionalized PES mixed with different amount of PMPS, thermally treated to promote sol–gel crosslinking process to prepare the PES‐based hybrid materials. The trimethoxysilane grafted PES chains are covalently bonded with the well‐defined trimethoxysilane groups of PMPS. The chemical structure of the prepared PES and PMPS is confirmed by Fourier transform infrared analysis. The morphology of the hybrids was investigated by scanning electron microscopy. The results of thermogravimetric analysis show that the thermal stability of the hybrid materials was significantly affected with the addition of PMPS. POLYM. ENG.

“…The preparation of hybrid materials from VTMS exploits both methoxide group hydrolysis/condensation to form the silica network and vinyl group polymerization to form the organic backbone. It has been demonstrated in the literature that the sequence of the two processes is important 22–24. If the hydrolysis/condensation step takes place before polymerization, the growth of ample silica domains is favored and the vinyl groups are less available for radical polymerization.…”

The copolymerization of zirconium oxo‐clusters (Zr12) with 3‐methacryloxypropyl (trimethoxy)silane (MPTMS), using a Si/Zr molar ratio of 4, was investigated. The hybrid samples were prepared both with and without organosilane prehydrolysis. Differential scanning calorimetry (DSC), multinuclear liquid, and solid state NMR analyses and Fourier transform infrared (FTIR) spectroscopy were used to characterize the hybrid materials and study the influence of synthesis conditions on condensation and polymerization. The degree of condensation (DOC) of the silsesquioxane network and the polymerization yield are generally high. However, the organosilane prehydrolysis step leads to the reduction of the extent of phase interaction, thus favoring the phase separation between silica‐zirconia‐based domains. Dynamic mechanical spectroscopy (DMS) analyses were performed on the hybrid polymers obtained by means of the two synthetic pathways. The sample prepared without the organosilane prehydrolysis step presents a higher glass transition temperature (Tg) than the one with silane prehydrolysis. By heating above the Tg, the samples retain shape and size, due to the lack of viscous flow. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
