| Abstract: |
| The classification and properties of cellulose and its derivatives were briefly introduced and he the corrosion inhibition mechanism of cellulose was reviewed and summarized. Then, the various corrosion inhibition effects of plant cellulose and its derivatives as well as nano-cellulose in the corrosion inhibition system were systematically summarized. At the same time, based on the structural characteristics of plant cellulose and nano-cellulose, the application prospect of bacterial cellulose in metal corrosion inhibition system was discussed. Finally, it was proposed that carboxymethyl cellulose, hydroxyethyl cellulose and their derivatives were widely used, but greatly affected by temperature. Cellulose nanocrystals have good application prospects in metal protection, and are also the focus of future research. Bacterial cellulose is expected to be a new type of corrosion inhibitor with high efficiency and green property, but has not been paid enough attention by researchers. The preparation method and slow-release mechanism of bacterial cellulose need to be further studied. |
