A study on the preparation of polyvinyl alcohol thin-film composite membranes and reverse osmosis testing

Physical stabilisation of electrospun poly(vinyl alcohol) nanofibres: comparative study on methanol and heat-based crosslinking

“…Despite having advantageous properties, it suffers from instability in water and hence this is a major challenge to its full application potential [7]. Crosslinking of electrospun PVA nanofibres is carried out to remove this problem by many researchers [1,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Crosslinking forms a three-dimensional network by joining polymer chains with one another and therefore increases fibre stability as well as other physical properties.…”

Study on a novel polyamide-urea reverse osmosis composite membrane (ICIC–MPD)I. Preparation and characterization of ICIC–MPD membrane

“…In general, the strategy that has been used extensively to improve the surface performance of RO membrane is to either develop the new materials of the skin layer or modify the surface of commercial RO membrane. For example, RO membranes of better antifouling ability have been obtained via changing the surface charge [3,4] or improving the hydrophilicity [5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”

New type of nanofiltration membrane based on crosslinked hyperbranched polymers

“…Nevertheless, interfacial polymerization is still a key method to prepare commercial NF membranes and this technology achieved quick development in the last 10 years [15]. What's more, in the past 20 years, the chemical composition of the active layers of most commercial NF membranes has been limited to polyamide materials [16], although some additional polymeric materials such as sulfonated polyether-sulfone (SPES), polyvinyl alcohol (PVA) derivatives, sulfonated polyphenylene oxide (SPPO), and chitosan derivatives have also been developed [17][18][19]. The most serious drawback of aromatic polyamides is the proneness to organic fouling.…”
