摘要(Abstract)：

本文使用两种厚度镍酸钐膜(30、60 nm),在实海长期浸泡，研究实际稳定性和电化学性能。结果表明镍酸钐膜在海水中长期浸泡，局部有溶蚀现象，对应样品存在失重。循环伏安曲线存在明显的氧化还原峰，30 nm SNO样品氧化还原峰与60 nm SNO样品出峰位置相差约0.2 V,30 nm SNO样品比60 nm SNO样品的交换电流密度大一个数量级，可知30 nm SNO样品电子转移活性更高，更容易发生氧化还原反应。交流阻抗测试结果表明样品存在巨大的电阻变化，30 nm SNO样品比60 nm SNO样品反应更快，电子转移电阻更小。配对电极电场响应测试结果表明响应波形不规则、且漂移较大，两种厚度样品均未能正常响应。
