“…A good example of superhydrophobic materials is poly(acrylonitrile-co-acrylic acid) (PAN/AA) membrane (Lv et al, 2022). Polyacrylonitrile-co-acrlic acid could effectively hinder contact between oil and membrane, thereby acting as a repulsive liquid phase (oleophobic) with great potential for oil removal.…”

“…Polyacrylonitrile-co-acrlic acid could effectively hinder contact between oil and membrane, thereby acting as a repulsive liquid phase (oleophobic) with great potential for oil removal. The main reason for their oleophobicity could be attributed to their functionalized surface and size-sieving effect (Lv et al, 2022). As illustrated in Figure 13a, when applied for oil removal in the water containing oil substance, the water quickly passed through the PAN/AA copolymeric membrane while the oil substance was blocked, and the percent removal expressed in the form of the chemical oxygen demand (COD) reached more than 90% (Figure 13b,c).…”

Increasing water pollution due to anthropogenic activities prompts the quest for an effective water treatment method. Polymeric materials have gained attention as adsorbents for water purification. Membranes are majorly made from homopolymeric materials. However, recent studies have focused on using copolymeric materials for improved performance. In this review, the basics of copolymerization including various types of copolymers, synthetic approaches, and their applications in various water pollutants removal are discussed in detail. Advances in water treatment technology using copolymeric materials as adsorbent/membranes in the last 4 years are covered with insights into the future outlook and areas of improvement in terms of copolymer composites for water treatment. Studies from the literature did not only reveal effectiveness of copolymer as a flocculant/antifouling materials and in removal of selective toxic metals, oil, and microbes but also demonstrated recyclability of the copolymer sorbents/membrane. Full exploration of unique copolymer textural and structural properties could lead to great advancement in water treatment process.Practitioner Points The copolymer types and synthetic methods are discussed. Application of copolymer as adsorbent/membranes for water treatment is presented. Recent advances show good pollutants removal for toxic metals, oil, and organics. Copolymer composites have great potential as adsorbent/membranes for future use in water treatment processes.

“…It was found that the hydrophilicity of the nanofiber membrane was significantly enhanced. 11 Graphene oxide was also doped in polyacrylonitrile nanofibers by electrospinning, and the acquired membrane showed a gradually decreasing water contact angle with the increase of GO content, which was conducive to water purification. 12 In addition.…”
