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 and Characterization of a Novel Biodegradable Epoxy Resin Modified with Epoxidized Oleic Acid
The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...
متن کاملFABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS
Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...
