三硅氧烷表面活性剂的合成、性能及应用

Synthesis,properties and applications of trisiloxane surfactants

简要介绍了三硅氧烷表面活性剂的结构,同时比较了其与普通碳氢表面活性剂在水中的表面活性;阐述了不同类型(阳离子型、阴离子型、两性以及非离子型)的三硅氧烷表面活性剂的合成研究情况;并且对其表面/界面性能、聚集性能、超级铺展性以及稳定性进行了讨论;介绍了其在农业化学品、微乳液、涂料、印刷油墨和锂电池等方面的应用;最后提出了三硅氧烷表面活性剂目前存在的问题、发展方向和应用前景。

Structures of trisiloxane surfactants were briefed,and its surface activity in aqueous solution was compared against that of conventional hydrocarbon chain surfactants.Recent progress in the synthesis of different types of trisiloxane surfactant（cationic,anionic,zwitterionic and nonionic） was summarized,and their properties with respect to surface/interface activity,aggregation,super-spreading and stability were discussed.Their applications in fields of agro-chemicals,microemulsions,coatings,printing inks and lithium batteries were introduced.Some existing problems,development trend and application prospects of trisiloxane surfactants were described.
