WCN23-0021 POLYVINYLPYRROLIDONE (PVP) ENHANCES THE HEMOCOMPATIBILITY OF POLYETHERSULFONE (PES) HEMODIALYSIS MEMBRANES

چکیده
When blood comes in contact with dialyzer membranes, the interfacial bioactivation reactions occurring at blood/membrane boundaries affect gross mechanisms related to thrombogenicity. In presence of biocompatible polymers, adhesion and subsequent interactions platelets, as well other serum components (e.g., proteins), are altered delay thrombus formation.

Polyethersulfone Hollow Fiber Membranes for Hemodialysis
Polyethersulfone (PES) is one of the most important polymeric materials and is widely used in separation fields. PES and PES-based membranes show outstanding oxidative, thermal and hydrolytic stability as well as good mechanical and film-forming properties. PES membranes could endure many kinds of sterilized methods, including epoxy ethane gas, steam, and γ-ray. Furthermore, PES-based membranes...
متن کاملAn Experimental Study on the Oily Wastewaters Treatment by Polyethersulfone (PES) Nanostructure Hollow Fiber Membranes
Oily wastewaters from oil refineries and oil distribution centers are one of the most important environmental concerns in recent decades; therefore, it is critical to treat these types of wastewaters. In this study, the performance of different polyethersulfone hollow fiber membranes in oily wastewaters treatment was investigated and the effects of operating conditions such as transmembrane pre...

متن کاملChitosan/Polyethersulfone Composite Nanofiltration Membrane for Industrial Wastewater Treatment
Chitosan/polyethersulfone (CS/PES) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. The Substrate membrane was prepared by phase inversion technique using polyethersulfone (PES) and dimethylacetamide (DMAc) as solvent with and without the addition of polyvinylpyrrolidone (PVP) as pore-forming agent. The effects of the composition of the c...
متن کاملEnzymatic Modification of Polyethersulfone Membranes
Enzymatic modification of polyethersulfone (PES) membranes has been found not only feasible, but also an environmentally attractive way to vary surface properties systematically. In this paper, we summarize the effect of modification layers on protein adsorption and bacterial adhesion on PES membranes and surfaces. The enzyme laccase was used to covalently bind (poly)phenolic acids to the membr...
