Oxidation of SWCNT-COOH?

01 April 2024 0 2K Report

Hello everyone. Could someone advise on the likelihood of high-purity SWCNT-COOH undergoing oxidation when stored in a refrigerator? I suspect that my SWCNT-COOH may have been oxidized due to the presence of potential water vapor inside the refrigerator at 4°C. Has anyone else experienced this issue? Thank you in advance for your insights.
