Preparation and characterization of HPEI-GO/PES ultrafiltration membrane with antifouling and antibacterial properties

Graphene immobilized enzyme/polyethersulfone mixed matrix membrane: Enhanced antibacterial, permeable and mechanical properties

“…2 was used to characterize the separation performance of the prepared membranes. The detailed procedure is described in our previous studies as shown elsewhere [4,5,31]. Briefly, the effective area of each flat sheet membrane pieces is 22.2 cm 2 and each membrane in testing was pressurized at 0.2 MPa for 1 h prior to performing the ultrafiltration experiments.…”

“…Polyethersulfone (PES) is an extensively used ultrafiltration membrane material which possesses excellent chemical resistance, good thermal stability as well as outstanding mechanical strength and has been widely applied in water treatment, biomedical and other industrial fields [1][2][3][4][5][6]. Nevertheless, fouling of polymeric membrane is a serious problem in the practical membrane separation processes, including deposition or attachment of suspended solids, colloidal particles, macromolecules and microorganisms [7,8].…”

Enhanced biofouling resistance of polyethersulfone membrane surface modified with capsaicin derivative and itaconic acid

“…Organic antibacterial materials can be covalently bonded to the membrane matrix to avoiding the above mentioned drawbacks. [24] The most commonly studied organic materials may comprise polycation [25], chitosan [26], halamine compounds [27], graphene oxide [28] and antibacterial enzymes or antibacterial peptide [22,29].…”

Surface photomodification of flat-sheet PES membranes with improved antifouling properties by varying UV irradiation time and additive solution pH

“…Polyethersulfone (PES), a high temperature amorphous thermoplastic polymer, has been widely used in manufacturing asymmetric membranes due to its mechanical, thermal and chemical resistances [1,2]. Nevertheless, this polymer is fouled during aqueous filtration due to its low hydrophilic character.…”

“…As a consequence, productivity and selectivity are negatively affected and therefore, membrane lifetime is reduced [2].…”
