| 摘要 |
The present invention relates to the use of charged cellulose nanocrystals for inhibiting corrosion of metals such as steel, with the charged cellulose nanocrystals being part of a corrosion inhibiting composition. The composition is a colloid comprising a dispersed phase that is solid and a dispersion medium that is liquid. The dispersed phase is the plurality of charged cellulose nanocrystals and the dispersion medium is a carrier. There is further provided a corrosion inhibiting composition including a carrier essentially consisting of water. The composition further includes an effective corrosion-inhibiting amount of charged cellulose nanocrystals in stabilized aqueous suspension. The cellulose nanocrystals have diameters in the range of about 4 nm to about 60 nm and lengths in the range of about 150 nm to about 350 nm. The composition may also include a corrosion inhibitor combined in a synergistically effective amount with the charged cellulose nanocrystals. |
