新型有机离子液体型缓蚀剂用于金属表面的抗蚀-抗菌研究
Research on corrosion resistance and antibacterial properties of new organic ionic liquid corrosion inhibitors on metal surfaces
金属在酸、碱、盐等腐蚀性介质中被腐蚀,特别是细菌等微生物极易对金属表面造成污损,其代谢产物将进一步加速金属腐蚀。因此,设计开发一款具有抑菌效果好、缓蚀效率高的有机缓蚀剂具有重要实践价值和科学意义。以对羟基苯甲醛与4-乙酰吡啶为原料,合成了一种具有抑菌作用且能在腐蚀性介质中形成致密保护层的离子液体型有机缓蚀剂,抑菌、防腐实验结果表明,该缓蚀剂能够有效吸附在金属基材上,具有高效防腐、有效杀菌的特点。
Metals are susceptible to corrosion in aggressive media such as acids,alkalis,and salts.Particularly,microorganisms like bacteria readily foul metal surfaces,and their metabolic products can further accelerate the corrosion process.Therefore,designing and developing an organic corrosion inhibitor that exhibits both excellent antibacterial efficacy and high inhibition efficiency holds significant practical value and scientific importance.Using p-hydroxybenzaldehyde and 4-acetylpyridine as starting materials,an ionic liquid-type organic corrosion inhibitor was synthesized.This inhibitor demonstrates antibacterial activity and the capability to form a dense protective layer in corrosive environments.Results from antibacterial and anticorrosion tests indicate that the inhibitor can effectively adsorb onto the metal substrate,exhibiting high-efficiency corrosion protection and effective sterilization.
