Preparation and characterization of a strong basic anion exchanger by radiation-induced grafting of styrene onto poly(tetrafluoroethylene) fiber

Anion exchange membranes based on semi-interpenetrating polymer network of quaternized chitosan and polystyrene

“…The results indicate that the formation of the semi-IPN structure benefits the mechanical strength of the membranes. However, the increased percent of the PS results in the decreased elongation at break of the membranes as PS is less flexible and similar result has been reported [42,43].…”

Preparation and application of acrylic acid grafted polytetrafluoroethylene fiber as a weak acid cation exchanger for adsorption of Er(III)

“…Besides, IEF also has particular textile structure that is more convenient to be used in practice [4]. Many organic fibers or modified fibers, such as polyacrylonitrile and polypropylene, have been used as the precursor fiber for the preparation of IEF [5,6]. But for some special application, they are limited by their poor thermal stability and low content of surface oxygen-containing groups.…”

Photoinduced grafting of vinyl benzyl trimethyl ammonium chloride on polyester nonwoven fabric with surfactant coating and its anion‐exchange properties

“…It is also considerable that this may have been caused by excess crosslinking generation at a high degree of grafting; this would reduced the anionexchange functionality of the graft chain. 22 From this result, the optimal degree of grafting in terms of AEC was found to be 80 6 5%. The maximum AEC of PET-g-VBTAC obtainable was approximately 2.2 mequiv/g; this was similar to that of the commercial anion-exchange resin (2.16 6 0.04 mequiv/g) and much higher than those of the nylon-g-VBTAC-HEMA fabrics ( 1.0 mequiv/g) prepared by a conventional cografting system.…”
