Herein, this paper details a comprehensive review on the biopolymeric membrane applications in micropollutants’ removal from wastewater. As such, the implications of utilising non-biodegradable membrane materials are outlined. In comparison, considerations on the concept of utilising nanostructured biodegradable polymeric membranes are also outlined. Such biodegradable polymers under considerations include biopolymers-derived cellulose and carrageenan. The advantages of these biopolymer materials include renewability, biocompatibility, biodegradability, and cost-effectiveness when compared to non-biodegradable polymers. The modifications of the biopolymeric membranes were also deliberated in detail. This included the utilisation of cellulose as matrix support for nanomaterials. Furthermore, attention towards the recent advances on using nanofillers towards the stabilisation and enhancement of biopolymeric membrane performances towards organic contaminants removal. It was noted that most of the biopolymeric membrane applications focused on organic dyes (methyl blue, Congo red, azo dyes), crude oil, hexane, and pharmaceutical chemicals such as tetracycline. However, more studies should be dedicated towards emerging pollutants such as micropollutants. The biopolymeric membrane performances such as rejection capabilities, fouling resistance, and water permeability properties were also outlined.

Appropriate wound care is pivotal in preventing wound and postsurgery infections, which remain a serious clinical problem. In this study, we report the successful fabrication of antimicrobial and biodegradable materials for possible use in the medical field. Amino functionalized polycaprolactone (PCL [Poly (CL-co-ACL)]) was synthesized via ring opening polymerization. This polymer was then functionalized via the pendant amine to induce antimicrobial efficacy. This was done through the grafting of poly(lysine) onto the amine as well as the quaternization of the amine using alkyl halides. The chemical structures of the synthesized monomers and polymers were confirmed using nuclear magnetic resonance (1 H NMR and 13 C NMR) spectroscopy and attenuated total reflection-Fourier transform infrared spectroscopy. The molecular weights of the polymers were determined using gel permeation chromatography. Nanofibre scaffolds were produced from the polymers using the electrospinning technique and these were characterized though scanning electron microscopy. The antimicrobial efficacy of the fabricated materials was tested against the Gram-positive (Staphylococcus aureus ATCC 25923) and Gram-negative (Pseudomonas aeruginosa ATCC 27853) bacteria using the disc diffusion and shake flask methods. The polymers demonstrated excellent antimicrobial efficacy. The fibers were exceptionally biodegradable which opens a lot of applications in the biomedical space.
