摘要
采用表面张力仪、粒径分析仪和紫外分光光度计研究了聚对苯二甲酸乙二醇酯-聚乙二醇共聚物(PET-co-PEG)与表面活性剂的相互作用,深入分析了PET-co-PEG对表面活性剂胶束的影响。结果表明:PET-co-PEG与阴离子表面活性剂AES之间具有强烈的电性相互作用,而非离子表面活性剂AEO9及两性表面活性剂LAB则均未与PET-co-PEG产生明显的相互作用。此外,PET-co-PEG的加入使得AES胶束的粒径显著减小。
The interaction between poly（ethylene terephthalate）-poly（ethylene oxide） copolymer（PET-co-PEG） and surfactants was studied through surface tension meter, particalsize analyzer and UVVis spectrophotometer, and the effects of PET-co-PEG on surfactant micelles were carefully investigated. The results indicate that there is strong electrostatic interaction between PET-co-PEG and anionic surfactant AES. In comparison, little interaction can be found between PET-co-PEG with nonionic surfactant AEO9 or ampholytic surfactant LAB. Moreover, micelle size of AES reduces abruptly with the addition of PET-co-PEG.
