Sodium chloride (NaCl) is the most abundant salt in seawater, which showed the strongest effect in lowering the viscosity of wormlike micellar solutions (WMS) compared to other investigated ionic compounds. In this study, we examined the effect of NaCl addition on the structure of wormlike micelles using the semi-quantitative rheo-structure relations provided by the reaction-reptation model. Prior to addition of NaCl, the structure of wormlike micelles ([CTAB]/[NaSal] = 1 at [CTAB] = 100 mM) in the solution were investigated at different temperatures (25 ℃ ≤ T ≤ 60 ℃). At higher temperatures, shorter relaxation times and lower ratio values for the local minimum of loss modulus $\left(G_{min}^{\text{'}\text{'}}\right)$ over the plateau modulus ($G_0^{\text{'}}$) were observed. Our results showed that while the zero-shear viscosity of WMS decreased by NaCl addition (S = [NaCl]/[CTAB] varied from 0 to 9), its first critical shear rate and shear stress plateau were observed at their higher values. In addition, while the relaxation time of WMS decreased by adding NaCl, values of $G_{min}^{\text{'}\text{'}}/G_0^{\text{'}}$ did not change accordingly. These results indicate that branch points were formed upon the addition of NaCl and led to the shorter relaxation time and lower zero-shear viscosity.

氯化钠（NaCl）是海水中最丰富的盐，与其他研究的离子化合物相比，它在降低蠕虫状胶束溶液（WMS）的粘度方面显示出最强的作用。在这项研究中，我们使用了反应-排斥模型提供的半定量流变-结构关系，研究了添加氯化钠对蠕虫状胶束结构的影响。之前加入NaCl，蠕虫状胶束的结构的（[CTAB] / [鼻]  =  1在[CTAB]  =  100 毫摩尔）的溶液中在不同温度下研究（25℃≤Ť  ≤  60  ℃）。在较高温度下，较短的弛豫时间和较低的比率值（损耗模量的局部最小值）$\left(G_{米\mathrm{一世}ñ}^{\text{'}\text{'}}\right)$ 在高原模量（$G_0^{\text{'}}$）进行观察。我们的结果表明，尽管加入NaCl会降低WMS的零剪切粘度（S  =  [NaCl] / [CTAB]在0到9之间变化），但它们的第一临界剪切速率和剪切应力平稳期均处于较高值。此外，虽然通过添加NaCl可以减少WMS的弛豫时间，但$G_{米\mathrm{一世}ñ}^{\text{'}\text{'}}/G_0^{\text{'}}$没有相应地更改。这些结果表明，在添加氯化钠时会形成分支点，从而导致较短的弛豫时间和较低的零剪切粘度。
