“…Modification on the surface of NPs by zwitterion amino acid compounds such as L‐cysteine (Cys) exhibit excellent characteristics. In addition, many researchers reported fouling mitigation when using zwitterion amino acid in the membrane application (Shevate et al., 2017a; Yang, 2017). The zwitterion interaction forms a firm hydration shell on the membrane surface that serves as a shield to keep foulants from coming directly and significantly reduce protein adsorption (He et al., 2018).…”

Membrane technology has been extensively applied for protein separation. A membrane with reliable filtration performance and high removal efficiency is required. In this study, an ultrafiltration (UF) membrane was fabricated by dry‐wet phase inversion to incorporate copper oxide nanoparticles (CuO NPs) with a different ratio of L‐cysteine (Cys) in polysulfone (PSf). The characterization of the membrane involves using scanning electron microscopy (SEM), water contact angle, water content, pore size, and porosity analysis. The membrane performance evaluation includes flux permeation and bovine serum albumin (BSA) removal as a protein foulant. The membrane antifouling feature was examined by dynamic filtration of BSA. It was found that the Cys to CuO NPs ratio of 1.7:1 gives an optimal value on flux permeation and protein removal. The membrane exhibited high removal of BSA with 96.3%, and optimum water flux was achieved at 173.3 L/m2h, respectively. The highest permeability of aqueous BSA permeate at 500 ppm was about 111 L/m2h and 82.5 L/m2h for 1000 ppm. The enhancement of PSf‐Cys‐CuO membrane performance could be due to its lower contact angle (68.7°), high porosity (68%), and ideal pore size (46 nm) as well as showing good morphological structure. Most significantly, the inclusion of Cys improves antifouling capabilities. The membrane showed a lower chance of fouling based on the evaluation of the relative flux reduction and flux recovery ratio. Hence, the availability of Cys has a better impact on the polymer‐based membrane and seems promising for protein separation applications.

The main target of the present research work is synthesis of structurally modified polysulfone (PSF) membrane with good anti‐fouling property. Fouling is a big problem in polymeric membrane field. This can be reduced by introducing the zwitter ionic structure on the polymeric backbone. In this research work, anti‐fouling of PSF membrane was taken as s challenge and successfully done via Friedel‐Crafts (FC) alkylation reaction. For the sake of comparison, the FC alkylation reaction of chloroethylamine (CEA) and chloroaceticacid (CAA) onto PSF backbone was done in a single step and two step reactions in the presence of AlCl3 as a catalyst. The structurally modified PSF was characterized by FT‐IR spectrum, 1H‐NMR spectrum, XPS, EDX, SEM, DSC, TGA, WCA and POM. The porosity and antimicrobial properties of simultaneously acid and amine functionalized PSF membrane was tested. The single step reaction exhibited a peak in the FT‐IR spectrum at 1669 cm−1 corresponding to the zwitter ionic structure. The same peak was absent in the two step reaction. The PSF4 system showed the lowest WCA of 32.4° and confirmed the increase in hydrophilicity of the membrane material. The thermal stability of the PSF before and after the structural modification reaction was internally analyzed and compared with the literature values.
