The Effect of Polyethylene Glycol and Nanoclay on the Rheological Behavior of Dispersing Cationic Polyurethane Nanocomposites
Cationic waterborne polyurethane as a new dispersing polymer was synthesized by using relatively hydrophilic polyols. Dispersing cationic polyurethane (DCPU) nanocomposites were prepared using isophorone diisocyanate (IPDI), polyethylene glycol (PEG) with different molecular weights (Mn=200, 400, 600,and1000 g/mol), N-methyl diethanolamine (MDEA), dibutyltin dilaurate (DBTDL) and different perc...

In this paper, a series of well-defined polyethylene-b-polytetrafluoroethylene diblock copolymers (PE–b– PTFEs) were prepared by a coupling reaction of hydroxyl-terminated polyethylene (PE–OH) and isocyanateterminated 1H,1H-perfluoro-1-tetradecanol (PFDO–NCO). PE–OH was prepared by the coordination chain transfer polymerization using 2,6-bis[1-(2,6-diisopropylphenyl)imino ethyl] pyridine iron (...
متن کاملAnti-fouling behaviors of surface functionalized high density polyethylene membrane in microfiltration of bovine serum albumin protein
An essential characteristic for high performance inherently hydrophobic membranes such as microporous high density polyethylene (HDPE) membranes is to have a hydrophilic surface. In this project, wet chemical functionalization as a facile and effective method was developed to give a hydrophilic property to HDPE membranes using polar functional groups. KClO3, K2Cr2O7 and KMnO4 were selected as o...
متن کاملPerformance and Structure of Thin Film Composite Reverse Osmosis Membranes Prepared by Interfacial Polymerization in the Presence of Acid Acceptor
During interfacial polymerization (IP) reaction between m-phenylenediamine (MPDA) and trimesoyl chloride (TMC), a by-product, i.e. hydrochloric acid can produce. This produced acid diffuses back in aqueous phase and protonates MPDA and reduces its reactivity that results in lowering of polymer yield and performance of membrane. Further, for getting consistency in reverse...
