Preparation and characterization of nano-porous Polyacrylonitrile (PAN) membranes with hydrophilic surface
Polyacrylonitrile (PAN) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (IGEPAL) as an additive in the casting solution. The membranes were prepared from PAN/IGEPAL/1-Methyl-2-pyrrolidone (NMP) via phase inversion induced by immersion precipitation technique. Pure water was used as coagulation medium. The effects o...

متن کاملPreparation, Characterization and Application Studies of PVDF- PS Ultrafiltration Membranes
Polyvinyledenefluoride–polystyrene (PVDF/PS) blend ultrafiltration membranes were prepared using phase inversion technique. Casting solutions were prepared with different compositions of polyvinylidene fluoride (PVDF) and polystyrene (PS) both in the presence and absence of the additive, polyvinylpyrolidone (PVP) using dimethylacetamide as solvent. The effects of compositions of PS and concentr...
متن کاملPreparation and characterization of MWCNT-COOH/PVC ultrafiltration membranes to use in water treatment
Polyvinyl chloride (PVC) membranes containing pristine and modified multiwall carbon nanotube (MWCNT) were prepared and characterized. MWCNT was modified in order to achieve well-dispersion within the membranes. The results of FTIR analysis revealed that MWCNT was successfully carboxylated. The FESEM images indicated that the number of pores on the surface of membranes increased at the presence...
متن کاملUltrafiltration through Collodion Membranes
It is obvious that the factors considered in this paper render data obtained by ultrafiltration open to criticism unless they are checked by other methods and precautions are taken for the elimination of the vitiating effects which have been described. As regards the mechanism of ultrafiltration, the view of a sieve-like action as most experimental evidence indicates, is adequate, if all the fa...
