In the first year of this project, four different cellulose nanofibers were selected to be coated onto copper electrodes in order to test their ability to suppress electrochemical migration inhibition in water. The inhibition process was carefully observed, and the resulting hydrogel was evaluated. The outcomes indicated that coating electrodes with cellulose nanofibers can extend the inhibition time significantly. Furthermore, the correlation between inhibition performance and the formation of hydrogels was investigated. The good reversibility and conductivity of the coated cellulose nanofiber layers have been proven beneficial in preventing the short circuit of electrodes. These results contribute to a better understanding towards the use of cellulose nanofiber coating for protecting electronics against corrosion.
