摘要:

本文制备了一种含有偶氮苯基团的阴离子表面活性剂,其表面活性及对方解石矿物的润湿性能,可以用紫外光照射进行调控。在紫外光照射后,表面活性剂的临界胶束浓度(cmc)、最低表面张力(γcmc)、分子极限占有面积(Amin)增大,饱和吸附量(Гmax)和降低表面张力的效率(pC20)降低,对方解石的润湿能力增强。

关键词: 光敏, 偶氮苯, 表面活性剂, 光异构化, 表面张力, 接触角

Abstract:

A kind of photosensitive anionic surfactant was synthesized using 4-butylaniline, ethyl bromacetate andphenol. Its structure was identified by 1HNMR and its properties were also measured. It was found that photoisomerization of the surfactant occurred under the irradiation of ultraviolet light and its time to make balance was about 40 min. After the irradiation of ultraviolet light, the values of cmc, γcmc and Amin increased and the values of Гmax, pC20 and the contact angle on thecalcite surface decreased.

Key words: photosensitive, azobenzene, surfactant, photoisomerization, surface tension, contact angle
