“…The absorption peak at 1168 cm -1 comes from the C-O binding [27,29], originating from the PAN, and occurring in membrane 0 and rGO/PAN membranes. And the band at 1289 cm −1 appearing in the rGO spectrum comes from the stretching vibrations of the CO oscillator in the ether moiety [36].…”

The paper presents a method of obtaining composite polyacrylonitrile-based (PAN) membranes with the addition of reduced graphene oxide (rGO). The membranes were obtained using phase inversion method from a homogeneous rGO dispersion in a solution of PAN dissolved in N, N-dimethylformamide (DMF). The impact of the amount of rGO addition to the PAN matrix on the physicochemical, structural, transport, and separation properties and on fouling resistance was studied. Composite membranes, due to the method of preparation used and the addition of rGO, are characterized by very good transport properties (~390 L/m2 h) and by a high degree of protein retention (85%). Reduced graphene oxide has biocidal properties, which, as we have shown, depend on the size of nanoparticles and the type of microorganism. rGO/PAN membranes, on the other hand, show biostatic properties against Gram-negative bacteria (Escherichia coli), Gram-positive bacteria (Staphylococcuc aureus) and fungi (Candida albicans). Thus, the obtained composite membranes can be potentially used in water disinfection.

“…(3) An effective conductive network cannot be formed between graphene nanosheets. Sun et al conducted a more systematic study on “graphene’s corrosion promotion mechanism and its corresponded inhibition measures” by using the passivation principle to weaken or even eliminate the conductivity of graphene to solve its corrosion promotion effect, such as using fluorination modification, silane coupling agent treatment, silica coating, and low conductive polyaniline modification . Recently, he also studied the relationship between graphene’s corrosion promoting activity and percolation thresholds .…”

To solve the coating’s defects and achieve the goal of lightweight heavy-duty anticorrosive coatings, various two-dimensional (2D) nanomaterials are introduced to polymeric coatings to prepare long-term high-performance anticorrosive coatings. In this review, we concluded overall design ideas of the composite corrosion-resistant polymer coatings for a wide range of 2D nanomaterials and typically reviewed the development of graphene, boron nitride (BN), molybdenum disulfide (MoS2), zirconium phosphate (ZrP), MXene (Ti3C2T x ), and binary hybrid nanosheets (0D/2D, 1D/2D, 2D/2D, 3D/2D) in polymeric anticorrosive coatings. Finally, based on the above discussion, the challenges and outlooks in this promising field are featured from the perspective of chemical engineering.

“…The epoxy coatings with 0.6wt.% F-doped rGO demonstrated long-term anticorrosion effect to steel. [206] Normally, doping of N atoms into the graphene lattice leads to enhanced electrical conductivity and better electrolyte wetting, both of which may favor the corrosion. However, some reports pointed out that the substitutional doping of N atoms into the graphene lattice via chemical vapor deposition (CVD) can lead Reproduced with permission.…”

Corrosion of metals induces enormous loss of material performance and increase of cost, which has been a common and intractable issue that needs to be addressed urgently. Coating technology has been acknowledged to be the most economic and efficient approach to retard the metal corrosion. For several decades, polymers have been recognized as an effective anticorrosion coating material in both industries and scientific communities, as they demonstrate good barrier properties, ease of altering properties and massive production. Nanomaterials show distinctively different physical and chemical properties compared with their bulk counterparts, which have been considered as highly promising functional materials in various applications, impacting virtually all the fields of science and technologies. Recently, the introduction of nanomaterials with various properties into polymer matrix to form a polymer nanocomposite has been devoted to improve anticorrosive ability of polymer coatings. In this review article, we highlight the recent advances and synopsis of these high-performance polymer nanocomposites as anticorrosive coating materials. We expect that this work could be helpful for the researchers who are interested in the development of functional nanomaterials and advanced corrosion protection technology.
