Using of nanocomposite membranes composed of polymer and inorganic nanoparticles is a novel method to enhance gas separation performance. In this study, membranes were fabricated from polyester (PE) containing silica (SiO2) nanoparticles and gas permeation properties of the resulting membranes were investigated. Morphology of the membranes, SiO2 distribution a...

This study achieved a nanocomposite structure of nickel oxide (NiO)/titanium dioxide (TiO₂) heterojunction on a TiO₂ film surface. The photocatalytic activity of this structure evaluated by decomposing methylene blue (MB) solution was strongly correlated to the conductive behavior of the NiO film. A p-type NiO film of high concentration in contact with the native n-type TiO₂ film, which resulte...

Synthesized wurtzite ZnO nanostructures are incorporated on the poly (vinylidenefluoride-co-hexafluoropropylene) (PVdF-HFP) matrix, which improves thermal as well porosity nature of obtained thin film nanocomposite microporous polymer membrane (nanoCMPM). The shows a favorable effect crystallinity (Xc) 26.83% and melting temperature (Tm) 142.9 °C that conductivity electrolytes. Its characterist...

In this work, novel thin film composite membranes (TFCs) of poly (ether-6-block amide) (Pebax-1657) on a polyvinyl chloride (PVC) ultrafiltration membrane as support were prepared using inclined coating method for CO2 separation. Investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), ...

copper thin films with nano-scale structure have numerous applications in modern technology.  in this work, cu thin films with different thicknesses from 50–220 nm have been deposited on glass substrate by dc magnetron sputtering technique at room temperature in pure ar gas. the sputtering time was considered in 4, 8, 12 and 16 min, respectively. the thickness effect on the structural, morpholo...

We have built and characterized batch-processed polarization beam splitters (PBS), important optical components to separate the orthogonal TE and TM components of light. The devices were fabricated from thin-film, low-stress silicon nitride membranes and showed excellent performance. By stacking membranes, and a triple-layer PBS produced extinction ratios of 21 and 16dB for reflected and transm...

Epoxy/Single Walled Carbon Nanotube Nanocomposite Thin Films for Composites Reinforcement. (May 2009) Graham Leicester Warren, B.S., Texas A&M University Chair of Advisory Committee: Dr. Hung-Jue Sue This work is mainly focused upon the preparation, processing and evaluation of mechanical and material properties of epoxy/single walled carbon nanotube (SWCNT) nanocomposite thin films. B-staged e...
