Hydrophilic modification of polyethersulfone membranes by low temperature plasma-induced graft polymerization
A complete and permanent hydrophilic modification of polyethersulfone (PES) membranes is achieved by argon plasma treatment followed by polyacrylic acid (PAA) grafting in vapor phase. Both Ar plasma treatment alone and post-PAA grafting rendered a complete hydrophilicity to the PES membranes. The hydrophilicity of the membranes treated with only the Ar plasmas is not, however, permanent. In con...
متن کاملSurface hydrophilic modification of RO membranes by plasma polymerization for low organic fouling
Trimethylene glycol dimethyl ether (triglyme), a Polyethylene glycol (PEG)-like hydrophilic polymer, was deposited by plasma polymerization to reduce RO membrane’s organic fouling tendency. This method has the great advantage of achieving modification in one single step. A series of plasma deposition experiments were undertaken. The successful coating of the polymer was confirmed by X-ray photo...
متن کاملSurface Modification of PET Fabric by Graft Copolymerization with Acrylic Acid and Its Antibacterial Properties
Graft copolymerization of acrylic acid (AA) onto Poly(ethylene terephthalate) (PET) fabrics with the aid of benzoyl peroxide was carried out. The effect of polymerization parameters on the graft yield was studied. Percent grafting was enhanced significantly by increasing benzoyl peroxide (BP) concentrations up to 3.84 g/lit and then decreased upon further increase in initiator concentration. Pr...
متن کاملGraft copolymerization of methyl acrylate on chitosan: Initiated by ceric ammonium nitrate as the initiator-characterization and antimicrobial activity
Methyl acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, TGA methods. Evidence of grafting was confirmed by FTIR spectroscopy. The morphology evaluated by SEM. The thermal analysis indicated t...
متن کاملGraft Copolymerization onto Chitosan V: Grafting Ethyl Acrylate onto Chitosan Initiated By Ceric Ion and Its Anti Microbial Activity
Ethyl Acrylate was grafted onto chitosan by using the ceric ammonium nitrate as the initiator. The effect of initiator concentration, monomer concentration, time & temperature on % G and % E were studied. The grafted samples were characterized using FTIR, SEM, atomic force microscopy AFM and XRD methods. Xray diffraction showed changes in the crystallinity pattern of chitosan after the copolyme...
