In situ 29Si liquid-state nuclear magnetic resonance was used to investigate the ammonia-catalyzed hydrolysis and condensation of the single phenyltriethoxysilane (PTES) systems and the mixed tetraethoxysilane (TEOS)/PTES systems dissolved in methanol. By varying the molar ratio of the PTES, wat...
Chemical structure, microstructure and properties of organically modified silicate (ORMOSIL) antireflective (AR) coatings from phenyltriethoxysilane (PTES) and tetraethoxysilane (TEOS) were characterized. The reaction between PTES and TEOS was verified by means of FTIR, XPS, and 29Si NMR. N2 ads...
Acrylic acid based superabsorbent hydrogel was prepared using phenyltriethoxysilane (PTES) as polyfunctional monomer. Different amounts of PTES were incorporated in acrylic acid and irradiated at different doses upto maximum of 30 kGy. The crosslinked acrylic acid showed hydrogel properties and ...
Host–guest systems have been widely used for nanostructure construction; however, studying host–guest behavior by immobilizing the guest molecule on a substrate's surface faces great challenges. In this study, phenyltriethoxysilane (PTES) was selected as the ideal candidate to fabricate a...
Raman and infrared spectra of phenyltriethoxysilane and phenyltrimethoxysilane have been recorded. These silane coupling agents (SCAs) have been used as precursors to prepare sol–gels using acid or base as catalyst under different solution conditions. From the vibrational spectroscopic identifi...
Microparticles of organic–inorganic hybrid silica derived from a tri-functional ethoxysilane (phenyltriethoxysilane (PTES)) still have non-negligible amount of silanol (Si–OH) moiety after it is solidified in its outside appearance. Those residual silanol moiety formed in the Stöber process re...
In this research, three fibers including cellulose acetate (CA), CA–phenyltriethoxysilane (PTES) prepared via sol–gel electrospinning and sol–gel–based CA fibers immersed in PTES solution (dipped–CA–PTES) were prepared. The composition and morphology of the prepared fibers were evaluated b...
The density and refractive index were determined for four binary mixtures of dimethoxymethylphenylsilane with dimethyldimethoxysilane, dimethyldiethoxylsilane, methylvinyldiethoxysilane and ethenyltrimethoxysilane at different temperatures T = (298.15, 303.15, 308.15, 313.15 and 318.15) K and at...
A novel nebulizing spray hydrolysis approach was used for preparation of semi-transparent superhydrophobic coatings. Methyltrimethoxysilane was dissolved in water:ethanol mixture and ultrasonically sprayed on different substrates. Superhydrophobic coatings with a contact angle (CA) as high as 16...
The results of the previous research have shown that methyltrimethoxysilane is an effective agent for dimensional stabilisation of archaeological waterlogged wood. This paper presents an assessment of the effectiveness of MTMS in improving the biological resistance of archaeological waterlogged ...
Conservation of historic wooden monuments, especially regarding waterlogged archaeological wood, is a complex, long-term, multi-stage and also a quite difficult process. The main problem is poor dimensional stability of such artefacts due to a high degree of wood tissue degradation and its signi...
Experiments using archaeological wooden remains of a medieval “Poznań” bridge from the Lednica Lake, Wielkopolska Region, Poland, were performed to evaluate the stabilisation effect of methyltrimethoxysilane on waterlogged oak wood varied in the degree of degradation. Moreover, two types of t...
In this study, the surface modification of CaCO3 nanoparticles was performed by using a silane coupling agent methyltrimethoxysilane (MTMS) and effect of surface hydrophobicity on the stability of foam and emulsion was investigated. In order to confirm surface modification of CaCO3 nanoparticles...
