“…Among the graphite derivatives, a single-layer GO is a two-dimensional (2D) atom-thick material that has demonstrated great potential for water separation membranes [12][13][14][15][16]. In particular, GO nanosheets contain oxygenous moieties such as carboxyl (-COOH), epoxy (-O-), and hydroxyl (-OH) groups on surfaces and edges that can be exploited in fabricating functional nanocomposite membranes with high chemical stability, high hydrophilicity, and excellent antifouling and antibacterial properties [2,4,[17][18][19].…”

Graphene oxide (GO) nanosheets were utilized as a selective layer on a highly porous polyvinyl alcohol (PVA) nanofiber support via a pressure-assisted self-assembly technique to synthesize composite nanofiltration membranes. The GO layer was rendered stable by cross-linking the nanosheets (GO-to-GO) and by linking them onto the support surface (GO-to-PVA) using glutaraldehyde (GA). The amounts of GO and GA deposited on the PVA substrate were varied to determine the optimum nanofiltration membrane both in terms of water flux and salt rejection performances. The successful GA cross-linking of GO interlayers and GO-PVA via acetalization was confirmed by FTIR and XPS analyses, which corroborated with other characterization results from contact angle and zeta potential measurements. Morphologies of the most effective membrane (CGOPVA-50) featured a defect-free GA cross-linked GO layer with a thickness of ~67 nm. The best solute rejections of the CGOPVA-50 membrane were 91.01% for Na2SO4 (20 mM), 98.12% for Eosin Y (10 mg/L), 76.92% for Methylene blue (10 mg/L), and 49.62% for NaCl (20 mM). These findings may provide one of the promising approaches in synthesizing mechanically stable GO-based thin-film composite membranes that are effective for solute separation via nanofiltration.

The wear resistance of rubber composite materials has always been the focus of research. The wear resistance will not only affect the service life of products and the safety of equipment, but also have an important impact on the environment. In this work, the preparation and properties of wear-resistant rubber nanocomposites based on natural rubber (NR) were studied. It is dedicated to improving the wear resistance of NR composites. On this basis, the dispersibility of montmorillonite (MMT) hybrid materials in NR-based rubber composites was explored. SiO 2 @MMT, SiO 2 @MMT@KH560, PDA@GO, and MMT@GO hybrid materials were prepared, and the hybrid materials were applied to the NR/butadiene rubber (NR/BR) system, and NR/BR/hybrid material composite materials were successfully prepared. The results show that the interlayer spacing of MMT in hybrid materials increases, which effectively improves the dispersibility of MMT in rubber matrix. The tensile strength of NR/BR/MMT@GO composite material increased by 12%, the elongation at break increased by 25%, the DIN abrasion decreased by 16.5% compared with the optimum wear rubber formula, and the wear resistance was greatly improved. This work provides a feasible way for the design of functional polymer composites.

“…The PSF/PDA/aGO membrane showed a 54% lower fouling rate than the unmodified PSf, and demonstrated stability for 48 h of operation and interval cleanings using sodium hydroxide (NaOH) solutions. On the other hand, coating a binding agent such as polydopamine (PDA) and graphene oxide (GO) over the membrane rejection layer can strengthen the membrane anti-fouling properties [ 93 ]. For example, PDA-GO printed NF membranes (NF90) were constructed via an inkjet printing technique [ 93 ].…”

Incorporating polydopamine has become a viable method for membrane modification due to its universality and versatility. Fillers in their different categories have been confirmed as effective elements to improve the properties of membranes such as hydrophilicity, permeability, mechanical strength, and fouling resistance. Thus, this paper mainly highlights the recent studies that have been carried out using polydopamine and nanomaterial fillers simultaneously in modifying the performance of different membranes such as ultrafiltration, microfiltration, nanofiltration, reverse osmosis, and forward osmosis membranes according to the various modification methods. Graphene oxide nanoparticles have recently attracted a lot of attention among different nanoparticles used with polydopamine, due to their impressive characteristics impacts on enhancing membrane hydrophilicity, mechanical strength, and fouling resistance. Thus, the incorporation techniques of graphene oxide nanoparticles and polydopamine for enhancing membranes have been highlighted in this work. Moreover, different studies carried out on using polydopamine as a nanofiller for optimizing membrane performance have been discussed. Finally, perspectives, and possible paths of further research on mussel-inspired polydopamine and nanoparticles co-incorporation are stated according to the progress made in this field. It is anticipated that this review would provide benefits for the scientific community in designing a new generation of polymeric membranes for the treatment of different feed water and wastewater based on adhesive mussel inspired polydopamine polymer and nanomaterials combinations.
