Polysulfone/carbon nanotubes (PSF/CNTs) nanocomposite membrane was prepared via phase inversion induced by immersion precipitation technique. In addition, the surface of the CNTs were functionalized by polar carboxylic and amine groups to improve the interaction between the CNTs and the polymer matrix. For this purpose, the neat CNTs were chemically treated using sulfuric acid/ nitric acid (H2S...

New membrane types with well-controlled sub-nanostructures were developed from both polymeric and inorganic materials: carbon-based membranes, functionalized mesoporous oxide membranes and molecular sieving zeolite membranes. Regarding the carbon membranes, a novel carbon membrane with enhanced CO2 affinity was developed. The prepared membrane had a higher separation performance than that of th...

The carbon dioxide (CO2) separation can be enhanced by using modified materials like a deep eutectic solvent (DES) mesoporous silica SBA-15 in polymeric support i.e polysulfone via mixed matrix membranes (MMMs). pure and DES are potential candidates for the CO2 capturing their combination has not been reported yet. In this work, fresh was synthesized combining equal concentrations of Decanoic a...

In order to enhance salt rejection level and high pressure mechanical integrity, functionalized nanokaolin decorated multiwall carbon nanotubes (FNKM, 0-5 wt % loading) were incorporated into a cellulose acetate (CA) matrix using high temperature solution mixing methodology. Scanning electron microscopy (SEM), X-ray diffraction technique (XRD), thermo-gravimetric analyzer (TGA) and Fourier tran...

Ricinoloxazoline maleinate (OXA) was grafted by melt free radical grafting onto polyolefins and elastomers to produce new compatibilizers for polymer blends. Effects of initial monomer and peroxide concentrations on the degree of grafting, on the amount of residual monomer, and on the side reactions were investigated. Reactive compatibilizers could be prepared with a suitable choice of processi...

Thermally conductive polymeric materials with versatility are in high demand electronic devices. Whereas, the limited thermal conductivity (TC) and restrict development of such materials. Herein, hierarchical design assembly technology was applied to prepare multifunctional functionalized boron nitride/polyurethane multi-layer (m-FBN/PU) fibrous membranes higher quality quantity thermally netwo...

Nowadays, synthesis and application of Metal Nano-Clusters (MNC) attract great attention of scientists and technologists due to their unique electrical, magnetic and optical properties that differ from those of the bulk material. Nevertheless metallic nanoparticles are sometimes unstable and their stabilization is a crucial point to be solved in order to design new sensing devices which contain...

the gas separation performance of commercial ceramic titania and hybrid silica (hybsi®) membranes was assessed using the gas permeation and permporometry methods. results indicated that the hybsi® membranes have a hybrid surface containing regions covered by a polymeric matrix and others with inorganic pores. these membranes have high h2 selectivity, which increases significantly with temperatu...
