| 摘 要： | 以聚乙二醇和全氟壬烯为原料制备了全氟壬烯基聚乙二醇单醚和双醚,并以红外光谱进行表征.结果表明:全氟壬烯基聚乙二醇单醚和双醚都能使水的表面张力明显降低;C9F17O(CH2CH2O)18H和C9F17O(CH2CH2O)22H的质量浓度为1.0 g/L时,其水溶液表面张力分别为24.1和26.4 mN/m;随着聚乙二醇聚合度的增加,其水溶液的表面张力变大;C9F17O(CH2CH2O)18H水溶液的临界胶束浓度为1.32 g/L.

| Abstract: | Perfluorononylene polyethylene glycol mono- and diether, which can greatly decrease the surface tension of water, were prepared from polyethylene glycol and perfluorononene, and characterized by IR. The surface tensions of 1.0 g/L aqueous solution of C9F17O(CH2CH2O)18H and C9F17O(CH2CH2O)22H were 24.9 mN/m and 26.5 mN/m, respectively, which would rise with the increasing of the polymerization degree of polyethylene glycol. The CMC of aqueous solution of C9F17O(CH2CH2O)18H was 1.32 g/L. |
