采用极化曲线、循环伏安曲线和电化学阻抗谱等研究了微米铜、亚微米铜和纳米铜粉体制备的试样在模拟宫腔液中的电化学腐蚀行为。结果表明: 在模拟宫腔液中, 纳米铜试样最易被腐蚀, 亚微米铜试样次之, 微米铜试样最难被腐蚀; 纳米铜试样的腐蚀速率介于亚微米铜和微米铜试样之间, 这是因为在模拟宫腔液中, 纳米铜表面生成了较多的腐蚀产物膜, 从而导致其腐蚀速率降低; 纳米铜试样的Warburg阻抗最小, 其腐蚀过程由动力学因素控制, 微米铜试样的Warburg阻抗最大, 其腐蚀过程主要由扩散过程控制; 选用纳米铜作为制作宫内节育器的材料更有利于铜离子扩散进入模拟宫腔液中, 有助于延长宫内节育器的使用寿命。
