摘要:

通过N,N-二甲基十二烷基胺(DMA)、十六烷基三甲基溴化铵(CTAB)以及肉桂酸钠(CA)构建了一种具有CO2/N2-紫外光双重响应的蠕虫状胶束体系。研究发现DMA、CTAB、CA组成的体系黏度较低,不能形成蠕虫状胶束,向上述体系中引入CO2后会引起DMA的质子化,从而导致表面活性剂分子在体系中的排列方式发生改变并形成蠕虫状胶束。在通入N2后蠕虫状胶束会可逆地转变为球状胶束。进一步研究发现,由于CA可以在紫外光的照射下实现反式结构与顺式结构的转变,对已经形成的蠕虫状胶束体系照射紫外光也可以形成黏度较低的球状胶束。

Abstract:

A worm-like micelle system with a dual response of CO2/N2-UV light was constructed by mixing N,N-dimethyldodecylamine (DMA), cetyltrimethylammonium bromide (CTAB) and sodium cinnamate (CA). Further research found that the system composed of DMA, CTAB and CA had low viscosity and could not form worm-like micelles. However, the introduction of CO2 can lead to the formation of worm-like micelles, which was due to the protonation of DMA that changed the arrangement of surfactant molecules in the system. After passing N2, the worm-like micelles would reversibly transform into spherical micelles. Ultraviolet light irradiation can transform worm-like micelles into spherical micelles with lower viscosity because CA can realize the transformation of trans-structure and cis-structure under the irradiation of ultraviolet light.

Key words: surfactants, micelles, ultraviolet light, carbon dioxide, responsive
