报道了苯甲醇对 CTAB/KBr胶束体系粘度的影响 ,利用 1 H NMR法研究了苯甲醇在 CTAB胶束中的增溶位置 .结果表明 ,在 KBr盐溶液中 ,随着苯甲醇的加入 ,0 .0 1 mol/L CTAB胶束体系的粘度增大至最大值 .对 CTAB分子的 1 H NMR分析表明 ,少量的苯甲醇增溶在棒状胶束的界面 ,促使胶束体积增大和相互缠结 ,体系的粘度随之增大 ;当苯甲醇浓度较高时 ,将增溶在胶束的栅栏层靠近极性头一侧 ,胶束发生棒 -球转变和解缠 ,体系的粘度降低
The effect of benzyl alcohol on the viscosity of CTAB / KBr micellar system was reported. The solubilization of benzyl alcohol in CTAB micelles was investigated by 1 H NMR. The results showed that with the addition of benzyl alcohol in KBr salt solution, The viscosity of 0,10 mol / L CTAB micellar system increased to the maximum value.IH NMR analysis of CTAB molecules showed that a small amount of benzyl alcohol solubilized at the interface of rod-shaped micelles and promoted the increase of micellar volume and entanglement The viscosity of the system increases. When the concentration of benzyl alcohol is higher, the solution will solubilize in the micellar barrier layer close to the polar head side, the micelles undergo rod-sphere transformation and unwinding, and the viscosity of the system decreases
