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.

在该项目的第一年，选择四种不同的纤维素纳米纤维涂覆在铜电极上，以测试它们抑制水中电化学迁移抑制的能力。仔细观察抑制过程，并对所得水凝胶进行评估。结果表明，用纤维素纳米纤维涂覆电极可以显着延长抑制时间。此外，还研究了抑制性能与水凝胶形成之间的相关性。涂层纤维素纳米纤维层良好的可逆性和导电性已被证明有利于防止电极短路。这些结果有助于更好地了解使用纤维素纳米纤维涂层来保护电子设备免受腐蚀。
