In 2022,Li, Wanjiang; Chen, Longbin; Dong, Jiao; Feng, Yancong; Wang, Yao; Li, Hao; Zhou, Guofu published an article in ACS Applied Polymer Materials. The title of the article was 《Water- and Heat-Induced Crack-Healing of UCST-Type Poly(acrylamide-co-acrylonitrile) with Intrinsic Controllability and Reversibility》.Application of 623-24-5 The author mentioned the following in the article:
Autonomic crack-healing technol. has become a common option for reconstructing polymer networks against mech. degradation, structure mismatch, material fatigue, and even performance failure, but how to precisely and easily trigger this healing process on the crack interfaces is still a huge challenge. Here, we first found an autonomic physicochem. crack-healing behavior featuring intrinsic controllability and reversibility, based on nonionic poly(acrylamide-co-acrylonitrile) [P(AAm-co-AN)] with an upper critical solution temperature (UCST). Under the fast synergistic action between extrinsic deionized water and heat, the scratched P(AAm-co-AN) layer fully returned to the original flat form and was reworked at least five times. Meanwhile, their corresponding optical and mech. performances also recovered almost 100%. In particular, the intrinsic thermoresponsiveness of P(AAm-co-AN) takes a leading role in this crack-healing process, in which both interchain transition and topol. entanglement come into play. It provides a facile, rapid, precise, green, and autonomic crack-healing strategy for improving polymer durability. The results came from multiple reactions, including the reaction of 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Application of 623-24-5)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others.
