运用流变学的研究方法研究了3-十六烷氧基-2-羟基丙基三甲基溴化铵(R16HTAB)/水杨酸钠(NaSal)/反式-3,4-二甲氧基肉桂酸(反-3,4-DMANa)构筑的光敏性智能蠕虫状胶束体系的流变性质.经过紫外光照,混合体系的剪切应力、弛豫时间、零剪切粘度均出现了随光照时间变化而变化的现象.这是因为反-3,4-DMANa在紫外光照下发生了反转,增加了位阻,使胶束变短,导致R16HTAB/NaSal/反-3,4-DMANa体系表现出光敏性.
The rheological properties of intelligent worm-like micellar system formed through the 3- hexadecyloxy-2-hydroxypropyl trimethyl ammonium bromide(R16 HTAB)/ salicylate sodium (NaSal) / trans-3, 4-dimethoxy cinnamic acid (anti-3,4-DMANa) mixedsolution were investigated using rheology research method. After UV irradiation, thechangesinthe shear stress, relaxation timeand zero shear vis-cosity of mixedsolutions take place with modifying light time. This is because of the cis-trans photoi-somerization of 3,4-DMANa, under the UV-Vis irradiation, a trans to cis reverse occurs and increases steric hindrance. The micelles become shorter, thus the R16HTAB/NaSal/ anti-3,4-DMANa system shows the photosensitive.
