[交流] 求助翻译

求助This was explained by assuming that, in the presence of the polymer
film, stripping of the metals was thermodynamically more
reversible as the oxidized metal species were retained close to
the electrode surface by the negatively charged sulfonic groups
of the Nafion film, so that the effects of diffusion were reduced.

借鉴前面的!

这一点可以从下面的假设得到解释:在聚合物薄膜存在时,金属的剥落在热力学上是更可逆的,因为氧化的金属原子被全氟磺酸薄膜中带负电的磺酸基团限制住在电极表面附近,其扩散效应降低了。

这是假设的解释,在聚合物薄膜存在下,溶出的金属在热力学中更容易可逆,而氧化金属物种通过全氟磺酸膜中带负电的磺酸基团保留在电极表面附近,因此扩散效率降低!

这可以这样解释:假设有聚合物薄膜保护着,金属剥脱的热力学过程就变得可逆,因为界面上金属的氧化层被全氟磺酸薄膜中带负电的磺酸基团限制住,所以扩散效应也就降低了。
