“…The crosslinked P84 MMMs containing cation exchange particles were prepared for adsorption of BSA and LZ [36]. Moreover many different inorganic particles such as titanium dioxide (TiO 2 ) [37], carbon nanotubes [38], silicon dioxide (SiO 2 ) [39], zinc oxide (ZnO) [40] and hydroxyapatite (HAP) [41] were dispersed in polymer matrix to prepare MMMs with microporous or macroporous structures.…”

“…13,15,[18][19][20][21][22] In recent time, significant efforts have been devoted in fabrication of polymeric MMM by using hydroxyapatite (HAP) as great potential filler for separation of protein. [23][24][25][26][27] HAP (chemical formula Ca 10 (PO 4 ) 6 (OH) 2 ) is inorganic component of the hard tissues in bones. 28 HAP is usually observed to be carbonate-substituted and calcium-deficient.…”

“…30,31 Since there has been a limited number of studies reported on used HAP for adsorptive MMM, this research is carried out to study the effect of different compositions of HAP embedded with PES matrix to adsorb BSA in a batch system. [23][24][25]27 The effect of different amounts of HAP to the structure and properties of the fabricated membrane was also evaluated. Adsorption equilibrium and kinetic studies have also been performed to understand the process of BSA adsorption onto fabricated membrane.…”

In this study, different amount of hydroxyapatite (HAP) was embedded into polyethersulfone (PES) matrix to prepare adsorptive mixed matrix membranes (MMMs). All fabricated membranes were characterised based on functional groups, morphology, overall porosity, water content, hydrophilicity and pure water flux. The relationship of equilibrium and kinetics of bovine serum albumin (BSA) adsorption onto fabricated membrane in a batch system was performed. The BSA adsorption equilibrium data is best described by Freundlich isotherm model followed by Langmuir isotherm model. The kinetics of the adsorption is well presented by pseudo-second-order kinetic model and followed by pseudo-first-order kinetic model. Among all membranes, fabricated PES/ HAP adsorptive MMM (K4) produced with 60 wt% HAP shows the best characteristic of membrane with higher water content, porosity and hydrophilicity, demonstrating the higher average pure water flux, j w of 29.12 m 2 l -1 h -1 ± 0.6 m 2 l -1 h -1 , adsorption capacity, q e of 26.54 (g BSA.g membrane -1 ) and adsorption kinetic rate, k 2 of 0.814 (h -1 ). The reusability of K4 membrane shows the most effective regeneration compare than other membrane. The results suggested that the PES/HAP adsorptive MMM can be effectively applied for the adsorption of BSA from aqueous solution and can offer high potential merit for application in membrane adsorption process.

“…Although modified surfaces containing capsaicin-mimic moieties can kill the attached bacteria, the residual dead bacteria will still contaminate the membrane, which may cause immune responses or inflammation [29,30]. Therefore, it is imperative to develop a novel membrane by introducing antifouling capabilities to antibacterial surfaces to achieve dual functions (antifouling and antibacterial).Recently, silane coupling agents have attracted a great deal of interest for their simplicity, versatility, and wide applicability [31,32]. It has been reported that silane coupling agents show excellent mechanical durability and antifouling property due to their special chemical structures, which can react with both inorganic fillers and organic substrates, and have been widely used to resist dust attachment and increase tensile moduli of composite materials in coatings industry [33,34].…”

Dual antifouling and antibacterial polysulfone(PSf)/polyethersulfone(PES) hybrid membranes were developed by the synergy of capsaicin-mimic N-(5-methyl acrylamide-2,3,4 hydroxy benzyl) acrylamide (AMTHBA) and vinyl triethylene (b-methoxy ethoxy) silane (VTMES). First, AMTHBA as a natural antimicrobial agent was incorporated into a casting solution via "microwave-assistance (MWA) in situ polymerization-blending" process to construct a hydroxyl-rich environment. Then, VTMES crosslinked to a hydroxyl-rich polymer matrix via hydrolytic condensation, and the influence of VTMES content on the hybrid membrane properties was systematically investigated. When the VTMES added amount was 1.0 wt %, the hybrid membrane achieved an optimal separation performance including a steady-state humic acid (HA) (5 mg/L) permeation flux of 326 L·m −2 ·h −1 and a rejection percentage of 97%. The antibacterial tests revealed that the hybrid membranes exhibited sustained bactericidal activity and effective inhibition of bacterial adhesion. Besides, the dual-functional membranes were clean as new after two-cycles filtration (with a cleaning efficiency of~90%), indicating that the network silicone film on the surface benefits the foulant repellence. Hopefully, the dual-functional membranes constructed in this study can be applicable to the pretreatment stage of water treatment.Polymers 2020, 12, 412 2 of 17 attachment of organic fouling and bacteria; (ii) bactericidal membranes for killing attached bacteria and preventing the formation of viable biofilm, which is principally against biofouling; and (iii) dual-functional bactericidal membranes for reducing both organic fouling and biofouling [13][14][15][16]. Among these, dual-functional bactericidal modification combining two strategies into one system is considered an ideal method. For example, Zhang et al.[17] designed a dual-functional antibacterial surface with a two-step surface modification strategy, aiming to acquire the properties of fouling resistance and antibacterial performance. Besides, Xie et al. [18] co-deposited polydopamine (PDA) and a zwitterionic polymer onto a polyethersulfone (PES) substrate and then immersed the surface in a AgNO 3 solution, leading to satisfactory antibacterial and antibiofouling properties. More recently, Wu et al. [19] synthesized a bifunctional membrane by incorporating silver-polydopamine nanohybrid (Ag-PDA) nanocomposites in a polysulfone membrane matrix. These results indicated the obvious advantages of dual functionality. However, due to the absence of strong bonding with surrounding polymers, active particles can be gradually leached out during operation, which could deteriorate the membrane antifouling efficiency [20]. In addition, the release of additional agents may have some potential impacts on the environment and human health [21].Capsaicin-mimic materials used as natural antifungal and antibacterial agents exhibit strong inhibition effects on various microbes and have been widely applied to resist marine or biomedical bacterial attachmen...
