The results showed that their surface tension decreased with an increasing alkyl chain length(n) at the 1-position of the cation. The values of surface tension covered a relatively wide range from 48.0 mJ/m2(PF6) to 35.7 mJ/m2(PF6).是什么意思_The results showed that their surface tension decreased with an increasing alkyl chain length(n) at the 1-position of the cation.
