“…The band assigned to Si-C bond is visible in the spectra of nanocomposites with treated silica at 1230 cm 71 . These results related to bands associated with neat nylon 6 and nylon 6/nanocomposites under study confirm the assignments proposed for aliphatic polyamides and Si bonds in the literature [44][45][46][47].…”

In situ anionic polymerization of °-caprolactam in the presence of SiO2 and silanated SiO2nanoparticles was promoted as a route for the synthesis of two series of nylon 6/SiO2 nanocomposites. The process was performed at 160°C well below the melting temperature of the nylon 6 ( Tm ~ 225°C) and initiated/activated with sodium dicaprolactamato-bis(2-methoxyethoxo)aluminate/ N, N′[methylene-di(4,4′phenylene)bis-carbamoyl]bis- δ-caprolactam system. The nanocomposites obtained exhibit higher onset decomposition temperatures than neat nylon 6 and a tendency of reduction of the polymer yields, degree of polymerization, water absorption and melting temperatures with silica content increasing. The crystallization temperature, Tc of the nanocomposites reaches a maximum value at 2.0 wt.% of the nanoparticles. The mechanical tests of nanocomposites revealed an increase in flexural modulus as a function of filler percentage and a decrease in notched impact strength by addition of the modified silica (over 4.0 wt.%) and unmodified silica. Furthermore, the flexural strength diminishes both the treated and untreated filler content is increased for concentration of ~ 4.0 wt.%

“…22,23 Santamaria et al 16 had also explained the effect of oxygen supply in terms of annihilation of defects consisting of oxygen vacancies. In our case, the sputterdeposition rate decreases rapidly upon supply of oxygen and saturates at above 5%, and this rapid decrease and saturation is close to that reported by Santamaria et al 17 Some other groups 20,24 reported gradual decrease even up to 45%, and we attribute this difference to the difference in sputter system used. To achieve uniform supply of gases we have placed a gas delivery unit with multiple nozzles close to target (see S2, ESI †).…”

A novel electrochemical method for deposition of ZrO(2) thin films is described. The films, 50-600 nm thick, were obtained by applying moderate positive or negative potentials (+2.5 V to -1.5 V versus SHE) on conducting surfaces immersed in a 2-propanol solution of zirconium tetra-n-propoxide [Zr(OPr)(4)] in the presence of minute quantities of water (water/monomer molar ratios in the range of 10(-5) to 10(-1)), which was the limiting reagent. Oxidative electrochemical formation of solvated H(+) and reductive formation of OH(-) catalyze the hydrolysis and condensation of the metal alkoxide precursor. The magnitude of the applied potential and its duration provide a convenient way of controlling the film thickness. The films consist of an amorphous phase, as revealed by XRD measurements. The effects of different parameters, such as the applied potential and its duration, the amount of added water and the current-time characteristics, were studied. A mechanism for the electrodeposition of the zirconia films which is in accordance with our findings is proposed.
