Polyacrylonitril (PAN)-supported chitosan (CS) nanocomposite membranes were prepared by cross-linking the CS with 3-aminopropyl-triethoxysilane (APTEOS) via sol-gel method. Pervaporative performances of the CS-SiO2/PAN membrane for dehydration of aqueous alcohol solutions were investigated. From SEM cross-sectional images of the membrane, the spongy pores and the finger-like pores we...

Polyethersulfone (PES) based nanocomposite nanofiltration membrane was prepared by immersion precipitation method and casting solution technique using  poly (acrylic acid) grafted-iron oxide nanoparticles (Fe3O4) as hydrophilic filler additives. For this purpose, iron oxide nanoparticles were modified by in situ polymerization of acrylic acid in aqueous solution by potassium persulfate as initi...

In this study 2-acrylamido-2-methylpropanesulfonic acid (AMPS) containing UV curable nanocomposite membranes were prepared by using the sol–gel method. Tetraethylorthosilicate (TEOS), and 3-(methacryloyloxy)propyl trimethoxysilane (MAPTMS) were used, respectively as an inorganic precursor and coupling agent. Cross linking agents such as poly(ethylene glycol diacrylate) (PEGMA) and ethylene glyc...

The paper examined Ti3C2Tx MXene (T—OH, Cl or F), which is prepared by etching a layered ternary carbide Ti3AlC2 (312 MAX-phase) precursor and deposited on polycaprolactone (PCL) electrospun membrane (MXene-PCL nanocomposite). X-ray Diffraction analysis (XRD) Scanning Electron Microscopy (SEM) indicates that the obtained material pure Ti3C2 MXene. SEM of PCL-MXene composite demonstrate random d...

The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties inorganic materials with reactivity, dielectric properties, durability, flexibility, processability polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydr...
