Bromo-substituted polyaniline (Br-PANI) is prepared by a novel strategy in which PANI is used as raw material, potassium bromate and potassium bromide as brominate regents. The obtained Br-PANI is characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, elemental analysis, FTIR, UV-vis spectra, and TGA. The results clearly indicate that Br has successfully attached to the benzene ring of PANI by chemical bond. The behavior of Br-PANI toward bacteria is characterized by plate counting, minimal inhibitory concentration, and minimal bactericidal concentration methods. The experimental results indicate that both doped and dedoped Br-PANIs have long-term antibacterial activities as compared to doped/dedoped PANI. What's more, the antibacterial abilities increase with increasing the Br/N molar ratio of the Br-PANI. Thus Br-PANI should be a kind of efficient and environmentally friendly antibacterial agent.

“…The chemistry of N ‐brominated compounds (i.e., molecules containing an NBr bond) is diverse, with such species being of significant importance in organic chemistry, and biochemistry . In addition, N ‐brominated biocidal polymers have also been developed for use in the disinfection of water ‐ and sterilization of stainless steel surfaces . Regarding the mechanisms by which N ‐brominated species react with organic molecules, while a number of reactions are known to proceed via ionic pathways (i.e., via the delivery of Br δ+ ), many also proceed via free‐radical mechanisms.…”

Homolytic NBr bond dissociation constitutes the initial step of numerous reactions involving N‐brominated species. However, little is known about the strength of NBr bonds toward homolytic cleavage. We herein report accurate bond dissociation energies (BDEs) for a set of 18 molecules using the high‐level W2 thermochemical protocol. The BDEs (at 298 K) of the species in this set range from 162.2 kJ mol−1 (N‐bromopyrrole) to 260.6 kJ mol−1 ((CHO)2NBr). In order to compute BDEs of larger systems, for which W2 theory is not applicable, we have benchmarked a wide range of more economical theoretical procedures. Of these, G3‐B3 offers the best performance (root‐mean‐square deviations = 2.9 kJ mol−1), and using this method, we have computed NBr BDEs for four widely used N‐brominated compounds. These include (BDEs are given in parentheses): N‐bromosuccinimide (281.6), N‐bromoglutarimide (263.2), N‐bromophthalimide (274.7), and 1,3‐dibromo‐5,5‐dimethylhydantoin (218.2 and 264.8 kJ mol−1). © 2015 Wiley Periodicals, Inc.

“…N -bromo-dimethylhydantoin-polystyrene beads were also tested in the removal of E. coli (ATCC 15597) and bacteriaphage MS2 (ATCC 15597-B1) from contaminated water according to the NSF-231 Standard Protocol for Testing Microbiological Water Purifiers. Beads were effective in the purification of 550 L and its production was scaled up to kilograms showing potential use as purification systems at industrial scale [ 269 ].…”

Antimicrobial Polymers in the Nano-World

Infections are one of the main concerns of our era due to antibiotic-resistant infections and the increasing costs in the health-care sector. Within this context, antimicrobial polymers present a great alternative to combat these problems since their mechanisms of action differ from those of antibiotics. Therefore, the microorganisms’ resistance to these polymeric materials is avoided. Antimicrobial polymers are not only applied in the health-care sector, they are also used in many other areas. This review presents different strategies that combine nanoscience and nanotechnology in the polymer world to combat contaminations from bacteria, fungi or algae. It focuses on the most relevant areas of application of these materials, viz. health, food, agriculture, and textiles.
