biostudies-literatureUnknown17(17)Li ZEpoxy resins used in reactors are prone to cracking and failure due to mechanical vibration, thermal stress, and ultraviolet radiation. Improving their resistance to damage is important to extend the service life of reactors. This investigation develops a self-healing imidazole-cured epoxy resin for reactors using epoxy microcapsules and amine microcapsules prepared by electrospraying-interfacial polymerization (ES-IP) microencapsulation technique. Firstly, this investigation studies the feasibility of using double nozzles for simultaneous spraying to improve the preparation of small-sized microcapsules. After successful synthesis, the healing performance of self-healing imidazole-cured epoxy based on the microencapsulated epoxy-amine chemistry was studied, focusing on the influence of thePolymers2391https://www.ebi.ac.uk/biostudies/studies/S-EPMC12431301biostudies-literatureSelf-Healing Imidazole-Cured Epoxy Using Microencapsulated Epoxy-Amine Chemistry.PMC12431301Zhan PLi GLi ZLu XZhang HDu GHao BYang SZheng FfalseSelf-Healing Imidazole-Cured Epoxy Using Microencapsulated Epoxy-Amine Chemistry.Epoxy resins used in reactors are prone to cracking and failure due to mechanical vibration, thermal stress, and ultraviolet radiation.
