WEB1 gen 2002 · Effect of the plasma grafting time on the graft concentration of PEG. Fig. 4 (a) shows the dependence of surface graft concentration and the [C O]/[CO] ratio on the RF power of the Ar plasma. The PEG concentration in the coating solution was fixed at 5 wt.% and the plasma treatment time at 60 s.
Surface modification of polypropylene membrane by polyethylene glycol ...
WEB1 set 2014 · The results clearly indicate that plasma graft-polymerization of PEG is an effective way for antifouling improvement of polypropylene membranes. Also, the results show that oxygen transfer changes in PEG grafted membranes are not significant. Polyethylene glycol. Polypropylene. Hydrophilicity. Plasma graft polymerization. Blood …

Plasma-Mediated Grafting of Poly(ethylene glycol) on Polyamide …
WEB15 mag 2007 · Plasma, Polymers. Abstract. A simple cold plasma technique was developed to functionalize the surfaces of polyamide (PA) and polyester (PET) for the grafting of polyethylene glycol (PEG) with the aim of reducing biofilm formation.
Repelling and ordering: the influence of poly(ethylene glycol) on ...
WEB10 ago 2017 · We report here the influence of the poly (ethylene glycol) (PEG) grafting density in model phospholipid monolayers on the adsorption behavior of bovine serum albumin and human fibrinogen, not only with respect to the amount of adsorbed protein, but also its orientational ordering on the surface.
Antifouling ability of polyethylene glycol of different molecular ...
WEB11 ago 2010 · PEG was grafted onto SiCl 4 plasma functionalized PET surfaces and the influence of molecular weight of PEG on grafting was investigated. PEG-grafted PET surfaces demonstrated increased surface area C–O peaks and increased hydrophilicity when compared to the unmodified PET.
Adsorption of Plasma Proteins onto PEGylated Lipid Bilayers: The Effect ...
WEB5 apr 2016 · Abstract. Lipid bilayers grafted with polyethylene glycol (PEG) of different sizes ( Mw = 750, 2000, and 5000) and grafting densities (1.6–25 mol % of PEGylated lipid in dipalmitoylphosphatidylcholine (DPPC) lipid molecules) were simulated with human serum albumin (HSA) using coarse-grained force fields.
Plasma-modified and polyethylene glycol-grafted polymers for …
WEBPlasma treatment and subsequent PEG grafting lead to dramatic changes in the polymer surface morphology, roughness and wettability. The plasma treated and PEG grafted polymers were seeded with rat vascular smooth muscle cells (VSMCs) and their adhesion and proliferation were studied.
