“…Furthermore, the hydrophilicity of PVDF surface was also enhanced when membranes were loaded with synthesized AgNPs using ginger extracts [43], which led to a lower contact angel by around 8 degrees [45]. In parallel, the modified PVDF membranes were evaluated for their antifouling properties using bovine serum albumin (BSA) filtration test which proved that the rejection rate of BSA solution exceeded 68% [43,46].…”

Silver nanoparticles (AgNPs) were successfully synthesized using the aqueous extract of the Paronychia argentea Lam (P. argentea) wild plant. The results showed that the conversion of Ag+ to Ag0 nanoparticles ratio reached 96.5% as determined by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), with a negative zeta potential (ζ) of −21.3 ± 7.68 mV of AgNPs expected to improve the stability of synthesized AgNPs. AgNP antibacterial activity has been examined against Streptococcus aureus (S. aureus) and Escherichia coli (E. coli) bacteria. The minimum inhibition concentration (MIC) was 4.9 µL/mL for both E. coli and S. aureus bacteria, while the minimum bactericidal concentrations (MBC) were 19.9 µL/mL and 4.9 µL/mL for S. aureus and E. coli, respectively. The synthesized AgNPs were incorporated in ultrafiltration polyvinylidene Fluoride (PVDF) membranes and showed remarkable antibiofouling behavior against both bacterial strains. The membranes were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and X-ray diffraction (XRD). The contact angle and porosity of the membrane were also determined. The efficiency of the membranes regarding rejection rate was assessed using bovine serum albumin (BSA). It was found in the flux experiments that membranes BSA rejection was 99.4% and 98.7% with and without AgNPs, respectively.

“…This is because the electret treatment increases the negative potential on the membrane surface, enhances the electrostatic repulsion with negatively charged BSA 40 and reduces the pollutants that block between the pores. In addition, the SEM morphology of Figure 5 also shows that the pore size and porosity of the membranes were increased after electret treatment, both of which have an impact on the membrane flux 41 . The evaluation indexes of anti‐fouling performance of filter membranes are shown in Figure 6d.…”

In this paper, electret treatment was used to enhance the electrostatic repulsion between the membrane and bovine serum albumin, so as to improve the anti‐fouling ability and recycling rate of the membrane. The polarization charge is provided by the dipole orientation of polyvinylidene fluoride (PVDF) materials, and the space charge is composed of the interfacial charge between the filler and the matrix and the bulk charge of the hollow structure of the multi‐walled carbon nanotubes. The results showed that after electret treatment, the surface potential of the membrane increased, the PVDF crystal type changed from α to β, and the crystallinity increased. Grafting of N‐vinylpyrrolidone onto multi‐walled carbon nanotubes (MWCNTs‐g‐PVP), which contain a large number of hydrophilic groups after modification, reduces the contact angle of the composite film from 86.9° to 62.7°. The pure water flux and flux recovery rate of MWCNTs‐g‐PVP/PVDF composite membranes after electret treatment was increased from 189.31 L·m−2·h−1 and 90% to 233.55 L·m−2·h−1 and 94.7%, respectively, and the rejection rate increased about 30%. Through the circulation experiment, it can be seen that the anti‐fouling performance and recycling rate of the membrane is improved, which is caused by electrostatic repulsion.

“…One way to prevent biofouling is by adding antimicrobial substances into the membrane matrix, such as titanium dioxide (TiO 2 ) nanoparticles, nanosilver (Ag), nano-sized hydrous manganese dioxide (HMO), and graphene oxide (GO) nanoparticles [17,18]. A research group led by Qiblawey investigated the effect of blending a polysulfone (PSf) poymer with a treated GO on the antibacterial activity of the PSf blend membrane [19].…”

Membrane properties are highly affected by the composition of the polymer solutions that make up the membrane material and their influence in the filtration performance on the separation or purification process. This paper studies the effects of the addition of pluronic (Plu) and patchouli oil (PO) in a polyethersulfone (PES) solution on the membrane morphology, membrane hydrophilicity, and filtration performance in the pesticide removal compound in the water sample. Three types of membranes with the composition of PES, PES + Plu, and PES + Plu + patchouli oil were prepared through a polymer phase inversion technique in an aqueous solvent. The resulting membranes were then analyzed and tested for their mechanical properties, hydrophilicity, antimicrobial properties, and filtration performance (cross-flow ultrafiltration). The results show that all of the prepared membranes could reject 75% of the pesticide. The modification of the PES membrane with Plu was shown to increase the overall pore size by altering the pore morphology of the pristine PES, which eventually increased the permeation flux of the ultrafiltration process. Furthermore, patchouli oil added antimicrobial properties, potentially minimizing the biofilm formation on the membrane surface.
