“…The static adsorption fouling was also tested to characterize the antifouling properties of the membranes. All tested membranes were cut into regular shapes of 3 × 3 cm 2 and immersed into 50 mL of a BSA solution (0.5 g/L, pH 7.4).…”

“…Recently, numerous researchers have proved that improving the hydrophilicity of the membrane surface could effectively reduce the membrane fouling problem. The preferential adsorption of water molecules by hydrophilic molecules or segments on modified membrane surfaces can form a protective layer: pollutants are prevented from contacting the hydrophobic membrane material and being adsorbed on the membrane surface . Hence, the key issue in expanding the application of UHMWPE membranes is improving the hydrophobic characteristics of UHMWPE.…”

In this work, a novel approach to improve the antifouling properties of membrane surfaces was developed. First, a polydopamine layer was attached onto the surface of an ultrahigh molecular weight polyethylene/fabric composite microporous membrane based on dopamine self-polymerization and adhesive behavior. Then, methoxy polyethylene glycol amine was covalently bonded with the polydopamine layer via a Schiff base reaction. The physicochemical properties of the modified composite membrane surface were investigated, and the results indicated this modification could effectively enhance the membrane surface hydrophilicity. Furthermore, the protein fouling resistance of both dopamine-coated and methoxy polyethylene glycol amine immobilized composite membranes was evaluated. It was found that a dopamine coating cannot obviously enhance the membrane antifouling properties due to its strong bioadhesion behavior. However, the antifouling properties of the composite membranes were significantly improved after being immobilized with a methoxy polyethylene glycol amine layer. Consequently, a layer-by-layer modified composite membrane with excellent antifouling property was obtained. The pure water flux and flux recovery ratio of the resultant membrane were 764 L m 22 h 21 and 83%, respectively. The aim of this paper was to provide an effective approach to optimizing the separation efficiency and antifouling performance of the ultrahigh molecular weight polyethylene/fabric composite membrane.

“…The hybrid membranes were prepared via non-solvent induced phase separation method by adding HSiO 2 into PVDF casting solution, the mass ratios of HSiO 2 and PVDF were 0%, 2%, 5% and 8%, which were denoted as PVDF, P-H-2%, P-H-5% and P-H-8%. The separation performances and antifouling properties of neat and modified PVDF UF membranes were tested according to our published paper [14]. 3 The morphology of HSiO 2 was shown in Fig.…”

“…Although the fouling mechanism is complex, the main reason for fouling formation is the hydrophobicity of the membrane surface [53,58]. Surface modification, polymer blend and ant other efforts have been attempted to improve the antifouling property and hydrophilicity of membrane [26,59,60]. As shown in Fig.…”

a b s t r a c tPoly (m-phenylene isophthalamide)/graphene oxide (PMIA/GO) composite nanofiltartion (NF) membranes were prepared via a facile phase inversion method. Structures, surface properties and hydrophilicities of the membrane were analyzed using FT-IR, XPS, AFM, SEM, water contact angle and Zeta-potential measurements. FTIR spectra indicated the existence of hydrophilic carboxylic acid and hydroxyl groups in the GO molecules. SEM pictures revealed the large and finger-like micro-voids formed in the sublayer of the NF membranes after adding GO. The zeta-potential and water contact angle results proved that PMIA/GO composite membranes had more negatively charged and greater hydrophilic surfaces. The pure water flux of the PMIA/GO (0.3 wt% GO) composite membrane (125.2 (L/m 2 /h)) was 2.6 times as high as that of the pristine PMIA NF membrane (48.3 (L/m 2 /h)) at 0.8 MPa with slightly higher rejections to all tested dyes and better fouling resistance to bovine serum albumin (BSA). This study gave an effective method for preparing composite PMIA NF membranes with high water flux and excellent antifouling property, which showed potential application in water treatment.
