“…S8 ) reveal that both iodine-loaded NRPOP-1 and NRPOP-2 inhibited the growth of gram-negative bacteria, PSA and EC, and gram-positive bacteria ML with similar extents while the polymer alone (control) had no effect on bacterial growth. These results suggest that a significant amount of loaded iodine that was released from the polymer during the incubation time (24 h) prevented the growth of bacteria 44 , hence supporting the idea of potential application of NRPOPs as delivery vehicles of iodine for antiseptic applications.…”

The capture and safe storage of radioactive iodine (129I or 131I) are of a compelling significance in the generation of nuclear energy and waste storage. Because of their physiochemical properties, Porous Organic Polymers (POPs) are considered to be one of the most sought classes of materials for iodine capture and storage. Herein, we report on the preparation and characterization of two triazine-based, nitrogen-rich, porous organic polymers, NRPOP-1 (SABET = 519 m2 g−1) and NRPOP-2 (SABET = 456 m2 g−1), by reacting 1,3,5-triazine-2,4,6-triamine or 1,4-bis-(2,4-diamino-1,3,5-triazine)-benzene with thieno[2,3-b]thiophene-2,5-dicarboxaldehyde, respectively, and their use in the capture of volatile iodine. NRPOP-1 and NRPOP-2 showed a high adsorption capacity of iodine vapor with an uptake of up to 317 wt % at 80 °C and 1 bar and adequate recyclability. The NRPOPs were also capable of removing up to 87% of iodine from 300 mg L−1 iodine-cyclohexane solution. Furthermore, the iodine-loaded polymers, I2@NRPOP-1 and I2@NRPOP-2, displayed good antibacterial activity against Micrococcus luteus (ML), Escherichia coli (EC), and Pseudomonas aeruginosa (PSA). The synergic functionality of these novel polymers makes them promising materials to the environment and public health.

“…The C–H and C≡N stretching vibrations are attributed to the PAN matrix [ 40 , 41 ], indicating that the as-electrospun product was supported by PAN polymeric chains. The appearance of the O–H, C–O–C, and C=O stretching vibrations confirmed the existence of GO [ 42 , 43 ]. In particular, the strong peak corresponding to the C–O–C and C=O vibrations further verified the high oxidation state on the GO nanosheets’ surface [ 43 ].…”

The emergence of antibiotic-resistant “superbugs” in recent decades has led to widespread illness and death and is a major ongoing public health issue. Since traditional antimicrobials and antibiotics are in many cases showing limited or no effectiveness in fighting some emerging pathogens, there is an urgent need to develop and explore novel antibacterial agents that are both powerful and reliable. Combining two or more antibiotics or antimicrobials has become a hot topic in antibacterial research. In this contribution, we report on using a simple electrospinning technique to create an N-halamine/graphene oxide-modified polymer membrane with excellent antibacterial activity. With the assistance of advanced techniques, the as-obtained membrane was characterized in terms of its chemical composition, morphology, size, and the presence of active chlorine. Its antibacterial properties were tested with Escherichia coli (E. coli) as the model bacteria, using the colony-counting method. Interestingly, the final N-halamine/graphene oxide-based antibacterial fibrous membrane inactivated E. coli both on contact and by releasing active chlorine. We believe that the synergistic antimicrobial action of our as-fabricated fibrous membrane should have great potential for utilization in water disinfection, air purification, medical and healthcare products, textile products, and other antibacterial-associated fields.

“…Therefore, designing an efficient strategy to trap and remove iodine from industrial wastewaters is of importance on a nationwide scale. A polymer was obtained for the purpose with Nvinylpyrrolidone and vinylacetate by one-step radical copolymerization with a regulated composition of the initial monomer mixture [112]. The N-vinylpyrrolidone-vinylacetate (N-VP-VA) copolymer was used as an absorbent to remove iodine from various solvents, including water, ethanol, cyclohexane, and petroleum ether.…”

The review summarizes the data on the main chemical and physiological properties of iodine and its capability of complexation with natural and synthetic polymers. Iodine is the best known antiseptic used to prevent and treat microbial infections. Its unique capability of complexation with certain polymers opens wide opportunities for targeted and prolonged delivery to target organs. Polymeric complexes with iodine have another color, other morphology, a higher electrical conductivity, and higher biological activity as compared with initial polymers. The formation of and ions is associated with iodine–polymer complexation. Iodine-containing biocompatible adhesive controlled-release formulations are designed as part of research into iodine–polymer complexes. The field is promising in terms of treating certain diseases because tolerance to iodine compounds does not usually develop in microbial cells.
