Abstract
- In order to investigate the effect of different copper surface state on the protection performance of triazole click-assembly film on Cu in circulating cooling water of power plants,the triazole inhibition films (CuMA-PR,Cu2OMA-PR,CuOMA-PR) were prepared via an in-situ click assembling reaction using p-toluenesulfonyl azide (MA) and propionic acid (PR) as assembly units on different copper surface state.Corrosion inhibition performance of the triazole inhibition films on copper substrate was evaluated by electrochemical method,corrosion coupon testing,SEM characterization and antibacterial property analysis.At the same time,the protective effect of Cu2OMA-PR on copper substrate in the circulating cooling water system of power plant was investigated.Results showed that Cu2O surface state was the best for the formation of triazole inhibition film(Cu2OMA-PR).The Cu2OMA-PR exhibited an excellent corrosion inhibition and antibacterial property on copper substrate within 21 d.The average inhibition efficiency of Cu2OMA-PR for copper in 3 weeks was 85.4%.Besides,Cu2OMA-PR could also effectively inhibit the proliferation of various microbial communities.
