Surface modification

CO2 plasma was used to modify hydrophobic polypropylene microporous membranes to create hydrophilic surfaces. Structural and morphological changes on the membrane surface were characterized by X-ray photoelectron spectroscopy and scanning electron microscope. Membrane performance was tested with wat

Reactive dyes are non-degradable and toxic to environments and human being, and their solutions have some color even after wastewater treatment. To remove toxic dyes, adsorption is common choice. In this study, to improve the adsorption capacity, the effect of cationic surfactant was studied to remo

This report describes the properties of surface-modified poly(vinylidene fluoride) (PVDF) membranes. These membranes were created by coating hydrophilic polymers on the support PVDF membrane to reduce the tendency to protein fouling. The modified membranes with different molecular weight cut-off (MW

The presented paper is a peer-review of plasma action on porous polymer membranes. Considering the plasma medium the discussion is split in two parts: i) the first shows some effects caused by action of non-polymerizing gases, i.e. polymer etching and/or alteration of surface character, and, ii) the

Surface modifying macromolecules (SMMs) were synthesized and blended into the casting solution of polyethersulfone (PES) membranes. The solution was cast to films on the glass plate. The cast films were placed in a temperature-controlled oven with forced air circulation to remove the solvent, before

Poly (ether sulfone) (PES) 50 kDa membranes were surface modified by irradiation with UV light (254 nm) in the presence of N-vinyl-2-pyrrolidine (NVP), 2-acrylamidoglycolic acid monohydrate (AAG) and 2-acrylamido-2-methyl1-propanesulfonic acid (AAP). The surfaces of the modified membranes were chemi

A simple grafting procedure was developed for surface modification of commercial polyamide reverse osmosis membranes. The modifications were monitored by spectral analysis. This technique was also used for study of membrane hydration. It was established that water interaction with surface functional
