A dual-stimuli responsive, wormlike micelle system was developed using a switchable selenium-containing surfactant, dihendecylcarboxylic acid sodium selenide (C₁₁-Se-C₁₁), and a commercially available surfactant, cetyltrimethyl ammonium bromide (CTAB). The solution showed a viscoelastic characteristic at low shear frequencies, and the synergism was significant when the concentrations of CTAB and C₁₁-Se-C₁₁ were 145 mM and 25 mM, respectively. Additionally, the system was fast and reversibly responded to CO₂ and redox dual stimuli, and it showed a circulatory gel/sol transition, which reflected changes in the self-assembly from entangled worms to rodlike micelles. Moreover, these transitions were switchable at least three times. The dual responsiveness of the solution allowed for precise control of the wormlike micelles, and these micelles will have a wide range of applications in the development of functional materials for pharmaceutical or biomedical materials.

基于含硒表面活性剂的CO ₂ / N ₂和氧化还原双重刺激的响应性，可转换蠕虫状胶束

使用可转换的含硒表面活性剂二癸基羧酸硒酸钠（C ₁₁ -Se-C ₁₁）和市售表面活性剂十六烷基三甲基溴化铵（CTAB）开发了一种双刺激响应的蠕虫状胶束系统。该溶液在低剪切频率下表现出粘弹性特征，并且当CTAB和C ₁₁ -Se-C ₁₁的浓度分别为145 mM和25 mM时，协同作用是显着的。此外，该系统对CO _2的响应速度快且可逆和氧化还原双重刺激，它显示出循环的凝胶/溶胶转变，反映了自缠结蠕虫到棒状微团的自组装变化。而且，这些转换至少可以切换3次。溶液的双重响应性使得可以精确控制蠕虫状胶束，并且这些胶束将在开发用于药物或生物医学材料的功能材料中具有广泛的应用。
