Multi-walled carbon nanotube (MWCNT) reinforced epoxy films were deposited on an aluminum substrate by a hot-pressing process. Three-point bending tests were performed to determine the Young's modulus of MWCNT reinforced nanocomposite films. Compared to the neat epoxy film, nanocomposite film with 1 wt % of MWCNT exhibits an increase of 21% in the Young's modulus. Four-point-bending tests were ...

We investigated the electrical and mechanical stability of flexible 6,13-bis (triisopropylsilylehtynyl)pentacene (TIPS-pentacene) thin-film transistors (TFTs) that were fabricated on polyimide (PI) substrates using cross-linked poly(4-vinylphenol) (c-PVP) and c-PVP/yttrium oxide (Y2O3) nanocomposite films as gate insulators. Compared with the electrical characteristics of TIPS-pentacene TFTs wi...

AbstmctMembranes supported by posts are used as vibrating elements of capacitive micromachined ultrasonic transducers (CMUTs). The residual stress built up during the fabrication process determines the transducer properties such as resonance frequency, collapse voltage, and gap distance. Hence, it is important t o evaluate and control the stress in thin film CMUT membranes. The residual stress ...

In this research thin film heterogeneous cation exchange membrane was prepared by interfacial polymerization of polyacrylic acid-co-iron nickel oxide nanoparticle son PVC based substrate. Spectra analysis confirmed graft polymerization conclusively. The SEM images showed that polymerized layer covers the membranes by simple gel network entanglement. Results exhibited that membrane water content...

the performances of two-phase polymer-liquid pebax®/polyethylene glycol (peg) and three-phase polymer-liquid-solid pebax®/peg/mwnt thin film composite membranes for co2 and ch4 permeation were studied. the effect of temperature and mwnt/pebax® ratio on single gas (co2 and ch4) permeability was investigated. the permeation of both gases was measured at different temperatures from 303 to 323 ˚k. ...

• Defect-free ZIF-8/GO/PIM-1 thin-film nanocomposite (TFN) membranes were fabricated. 2D ZIF/GO was produced by in situ growth of ZIF-8 on GO sheets as a continuous, uniform and thin layer. ZIF-8/GO composite results high dispersity compatibility ZG within PIM-1. PIM-1 infiltration into PVDF substrate avoided water pre-impregnation. TFN display PSI (228 kg m −2 h −1 ). In this work, film super-...

We have studied the surface-smoothing effect of an ultrathin germanium (Ge) layer on silver (Ag)-silica (SiO2) nanocomposite films for superlensing applications. Our experimental results indicate that inserting a thin Ge layer below the silver-silica composite films can reduce the final surface root-mean-squared (RMS) roughness to under 1 nm. Additionally, the metal nanostructure plays a role i...

Rapid population growth and the associated rise in industrialization food production have resulted a tremendously increased demand for clean water.

Solvent separations present one of the largest opportunities for membrane technologies. Currently, industries use millions tons solvents manufacture drugs, oils and chemicals. Multiple purifications must be conducted in order to purify products from solvents. However, existing separation processes are energy-intensive. Organic solvent nanofiltration (OSN) or solvent-resistant has emerged as an ...
