| 摘 要： | 本文报道了一种光敏型的阳离子表面活性剂（AZO），其分子结构中含有偶氮苯基团，并研究了光照对表面活性和泡沫性能的影响。经紫外光照射后，表面活性剂的饱和吸附量（Гmax）减小，临界胶束浓度（cmc）、最低表面张力（γcmc）和分子极限占有面积（Amin）增大；气泡数目增多，直径变小，发泡能力和泡沫稳定性降低。实验结果证实，该表面活性剂的表面活性和泡沫稳定性可以用光照进行调控。

| Abstract: | A cationic surfactant with an azobenzene group was prepared, which is AZO. Its molecule structure was identified by 1HNMR. The surface properties and foam stability were measured before and after UV light irritation. The photoisomerization of the azo-benzene group happened under the UV irradiation. After the UV irradiation, the Гmax values decreased, the values of cmc and γcmc increased and the foam stability decreased. The results showed that the surface properties and the foam stability of the surfactant can be controlled using the different light irradiation. |

| Keywords: | azobenzene surfactant surface tension foam stability |
