Protection Against Water-Induced Short-Circuit Failures of Electronics with Cellulosic Polymer Coating and Its Practical Applications

在该项目的第一年，选择了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，并评价所得水凝胶。结果表明，用纤维素纳米纤维涂覆电极可以显著延长缓蚀时间。此外，抑制性能和水凝胶的形成之间的相关性进行了研究。纤维素包覆层的良好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理解使用纤维素涂层保护电子设备免受腐蚀。

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.
