Abstract The present investigation is targeted to prepare nanocomposites based on binary blends of polyetherimide (PEI)-silicone rubber incorporated with varied loadings of nanotitanium dioxide particles. Nanocomposites have been prepared by melt blending process using twin screw extruder. Thermal properties of the developed nanocomposites have been investigated with the help of thermogravimetric analyzer (TGA) and dynamic mechanical analyzer (DMA). Scanning electron microscopy (SEM) is used to analyze the morphological properties of the nanocomposites. Mechanical properties (tensile strength, tensile modulus, elongation at break, impact strength) of the nanocomposites have been evaluated by universal testing machine (UTM). Mechanical testing results reveal that there is… More >

Abstract The interface properties of Fe(101)/zinc silicate modified by organo-siloxane (KH-570) was studied by using the method of molecular dynamics simulation. By calculating the temperature and energy fluctuation of equilibrium state, equilibrium concentration distribution, MSD of layer and different groups, and interaction energy of two interface models, the influencing mechanism on the interface properties of adding organosiloxane into coating system was studied at the atomic scale. It shows that the temperature and energy of interface oscillated in a small range and it was exited in a state of dynamic equilibrium within the initial simulation stage (t < 20 ps). It can… More > Graphic Abstract

Abstract Novel branched silicone methacrylate was developed. The mechanical and biological properties of the resin system were investigated to select the formula proportion with the best overall performance. The novel silicone-containing monomers were combined with an incremental sequence of glass filler concentrations in commonly used Bis-GMA/TEGDMA (50/50, wt./wt.) dental resin systems. Physicochemical properties, surface properties, antibacterial adhesion effect, anti-biofilm effect, protein adsorption, and cytotoxicity were evaluated. The results showed that BSMs did not affect the double bond conversion of dental resin, but could reduce volumetric shrinkage (p < 0.05). The BSM containing resins can resist protein and bacteria adhesion (S. Mutans)… More >

Abstract In recent years, more and more high-voltage overhead transmission lines were built passing through the karst regions in southwestern China. This type of special landform seems to have an adverse effect on the aging of the sheds of the line suspension composite insulators, which may lead to unexpected flashover and line tripping. In order to find out the particularity of the aging characteristics of insulators operating in the karst regions, samples in operation were selected from both the karst regions and the flatlands. Hydrophobicity, amount of surface contamination, and contaminant composition of the sheds were studied, then a comparison of… More >

Abstract In this investigation, a new silicone rubber-based MRE material was prepared to be used as a forming medium in manufacturing thin-walled complex- shaped Ni-based tubes through the bulging process. Thus, it is significant to investigate the effect of magnetic field intensity, magnetic field loading time, and angle on the mechanical properties of the prepared MRE material during the curing process. The obtained results showed that increasing the magnetic field intensity during the curing process can improve the orientation of the chain structure in the elastomer matrix effectively. However, its mechanical properties are the best under the corresponding magnetic field intensity… More >
