“…Inspired by the fast assembly of TA and Fe 3+ to form conformal coating, 29,30 a green and time-saving two-pot coating process was reported to form coordination network of TA-Fe 3+ on hydrophobic polypropylene (PP) substrate. 12 Compared to the one-pot coated membrane, the two-pot coated membrane has much better wettability (superhydrophilicity and underwater superoleophobicity), attributed to more adequate hydrophilic modification on both membrane outer surface and inner surface. It can be seen from Figure 8(a, b), two-pot treated membrane could be easily wetted by water droplets with WCA of nearly 0 , while the WCA of one-pot treated membrane was much larger (71.8 ).…”

“…Despite of the obtained inspiring results, some of the strategies might suffer from complicated procedure, expensive instruments, damage on membrane mechanical property, and weak interactions between coating layer and hydrophobic membrane surface. 12,27 Recently, plant polyphenol-inspired coatings have attracted increasing attention for membrane surface engineering, due to their ease of manipulation, versatility, and eco-friendliness. 28,29 Plant polyphenols as naturally occurring hydrophilic substances are abundant in plants, such as, green tea, fruits, flowers and vegetables, and also commercially available with low cost.…”

“…11,12 Moreover, superhydrophobic materials tend to be fouled by oil due to their oleophilicity, and the oil-water separation ux of the membrane gradually declines with the increasing cycle times. On the other hand, superhydrophilic membranes show the advantages of antifouling and reusability because they can effectively avoid or reduce external oil fouling by the formation of water barriers between the membranes and the oil phase; [13][14][15][16] in addition, to prevent bacteria from propagating in the pores of the membrane and causing clogging of the membrane pores, the membrane should have antibacterial property. Therefore, the development of hydrophilic and antibacterial PTFE membranes for wastewater treatment has broad application prospects.…”

“…With increasing industrial development and rapid population growth, discharging of oily wastewater from the activity and process of different industries such as, petrochemical, beverages, metal-finishing, metallurgical, food industries etc. is increasing at alarming rate, causing unprecedented harm to natural environment and human being and this is due to the fact that oil is flammable and also can decompose to form other harmful chemical, further aggravating pollution in the environment and adversely affects aqueous habitants and human's health [1][2][3][4][5][6]. Besides, Oily waste water is one of the factor that cause water pollution, which can have a concentration of 100-5000 mg/L or higher, depending on the nature of crude oil [7].…”
