“…Although the difference in normalized fl ux values between the membranes during the oil/water emulsion fi ltration is smaller than that during the BSA solution fi ltration, the TA-Fe III 0.06 coated membrane clearly shows higher foulingresistance against oil than the bare PES membrane; the DRs of the bare PES and TA-Fe III 0.06 coated membranes are 50% and 21%, respectively. Flux-recovery tests, performed with additional cleaning processes at 4,8,12, and 16 h, also indicate that the TA-Fe III 0.06 coated membrane has better performance in terms of fl ux-recovery ratio (FRR) than the bare PES membrane (Figures S5 and S6,Supporting Information). Thus, the TAFe III coating imparts higher antifouling properties against BSA and oil, as compared to the PES membrane.…”

“…J w2 , J w3 , J w4 , and J w5 are the water fl uxes recorded with the cleaned membranes at 4,8,12, and 16 h after fi ltration of the initial feed, respectively. As the value of FRR is larger, the antifouling property of the membrane is better.…”

“…The initial water fl ux values of the membranes were controlled to reach 70 LMH. To analyze the fl ux-recovery ability of the membranes, the membranes were cleaned by rinsing with water and placing them into the water-charged sonication bath for 10 min after the fi ltration experiments of 4,8,12,16 h. Then, water fl ux values were measured again with the cleaned membranes. Flux-recovery ability of the membranes could be evaluated by employing several parameters, including FRR, total fl ux-decline ratio (DR t ), reversible fl ux-decline ratio (DR r ), and irreversible fl ux-decline ratio (DR ir ).…”

water such as proteins, oils, and microorganisms is one of the major drawbacks in the membrane fi ltration because it can decrease the water permeation fl ux causing a subsequent increase in energy consumption for the fi ltration process. [ 2,3 ] Biofouling layer formed by the microorganisms on the membrane surfaces can clog and/or contaminate the membrane surfaces, thus preventing effective water purifi cation. [ 3h , 4 ] Rejection of heavy metal ions in waste water is another major concern in the membrane fi ltration process.Since membrane surface properties are key factors to the understanding and control of physico-chemical phenomena in the membrane fi ltration process, membrane surface modifi cations using blending, surface coating, and surface grafting methods have been applied to overcome the disadvantages of the process. [ 3a,d , 5 ] For example, a polymer with an ionic/ligand moiety was coated on a membrane surface to impart heavy metal ion removal properties, [ 5b ] and poly(ethylene oxide) (PEO) was incorporated into poly(acrylonitrile) (PAN) membrane by blending to enhance antifouling property against proteins. [ 3e ] Most of the membrane surface modifi cation strategies have focused on resolving one of the deleterious properties of each particular application. However, to our knowledge, any membrane surface modifi cation method to impart all the advantageous properties including the antifouling, antimicrobial, and heavy metal ion removal properties has not yet been reported.Plant-derived polyphenols have attracted signifi cant interests due to their broad chemical versatility, radical scavenging ability, metal ion complex formation, and antimicrobial properties. [ 6 ] They are easily obtained from general plants such as green tea, fruits, and fl owers, and also commercially available with low cost. [ 6a , 7 ] Polyphenol derivatives can be broadly used for surface coating applications because their catechol (1,2-dihydroxyphenyl) and/or gallol (1,2,3-trihydroxyphenyl) groups can easily adhere to the surfaces of substrates, forming covalent and/or noncovalent bonding structures. [ 5a,d , 6d , 8 ] For example, dopamine, a polyphenol derivative having the catechol moiety, has been applied as an antifouling coating material for fi ltration The membrane fi ltration process has received much attention as one of the most promising water purifi cation techniques. However, it still has several disadvantages, such as organic-, oil-, and biofouling, membrane contamination by microorganisms, and the diffi culty in rejecting heavy metal ions, which are closely related to the membrane surface properties. Various approaches have been used to prepare membranes with antifouling, antimicrobial, or heavy metal ion removal properties on their surfaces. However, membranes with all these properties have not yet been reported. It might be possible to prepare membranes with such multifunctional properties by modifying the membrane surfaces with various organic and/or inorganic functional materials using multiple chem...

“…9. Correlation of water content, K W , and NaCl sorption coefficient, K S , compared to data published by Yasuda et al [8]. K s was determined from kinetic desorption studies following equilibration in an aqueous salt solution at 298 K which contained 0.85 M NaCl, and K w was measured in pure water.…”

“…Zwitterionic polymers have received growing attention as a new generation of anti-biofouling desalination materials due to favorable resistance to protein adsorption and bacteria attachment [4][5][6][7][8]. Chang et al used interfacial polymerization followed by immobilization of zwitterions by crosslinking to prepare an antifouling NF membrane [4].…”
