为了构筑具有新颖应用性能的 Gemini 表面活性剂溶液体系，本文考察了季铵盐 Gemini 表面活性剂12（2OH）-3-12（2OH）在 SiO2微粒上的吸附行为及改性微粒的稳泡性能，并与 DTAB 和12-3-12的性能做比较。Gemini 表面活性剂在 SiO2微粒上的吸附效率明显优于传统表面活性剂，12-3-12＋SiO2体系的稳泡时间为 DTAB＋SiO2体系稳泡时间的5．07倍。12（2OH）-3-12（2OH）在 SiO2表面的表观吸附量和吸附效率与12-3-12相当，泡沫稳定性优于12-3-12＋SiO2体系。

To develop aqueous systems of Gemini surfactants with novel applications,the adsorption behavior of 12(2OH)-3-12 (2OH)on the SiO2 nanoparticles and the foam stability of the modified nanoparticles were investigated.The comparison was made with that of traditional quaternary ammonium surfactant DTAB and Gemini surfactant 12-3-12.The adsorption efficiency of Gemini surfactant at SiO2 nanoparticles surfaces is much higher than that of traditional surfactants.A longer foam stability time is achieved by 12-3-12+SiO2 system,which is 5.07 times of that of DTAB+SiO2 system.The adsorption amount and the adsorp-tion efficiency of Gemini surfactant 12(2OH)-3-12(2OH)is comparable with that of 12-3-12.Due to the presence of hydrogen bonds,the foam stability of 12(2OH)-3-12(2OH)+SiO2 system is superior to that of 12-3-12+SiO2 system.
