The corrosion inhibition process of the nanocomposite was explored using weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarisation (PDP). The corrosion inhibition performance of TiTR is a function of concentration and temperature. The results revealed that TiTR was 84.27% efficient in limiting MS corrosion at 1.0 g L−1 and 3 h. The TiTR acted as a mixed-type corrosion inhibitor and Langmuir isotherm indicated that TiTR was adsorbed on mild steel through physisorption by forming a monolayer of film. Surface morphology study of MS visually confirmed the protection of MS by TiTR through film formation.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"17 1","pages":"2562 - 2576"},"PeriodicalIF":1.8,"publicationDate":"2023-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88679535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effective response frequency band ranged from 10.12 to 11.30 GHz, and the reflection loss reached 10.94 dB at 10.96 GHz. The absorption mechanism was mainly owing to dielectric loss as no significant magnetic loss was observed.

Specifically, the hierarchical self-assembly of polyimide (PI) is followed by thermal annealing. Moreover, the structural evolution of PI under the various pyrolysis time was also comprehensively studied. It is noted that the as-prepared CSSs as anode composites for LIBs, especially CSS-5 h, exhibited extraordinary electrochemical properties, exhibiting a high reversible performance, great rate performance, and excellent cycling stability. As expected, the superior electrochemical capability can be ascribed to the synergistic effect of combining the nanoflower-like carbon superstructures with nitrogen contents. Such a method might encourage the inspirations to devise and obtain various heteroatom-modulated and hierarchical polymer-derived carbon composites for LIBs.","PeriodicalId":18232,"journal":{"name":"Materials Science and Technology","volume":"13 1","pages":"2525 - 2534"},"PeriodicalIF":1.8,"publicationDate":"2023-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88430883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
