Previous studies have shown that the plateau modulus G_p of the wormlike micelles formed in water driven by hydrophobic interactions is a constant upon heating, similar to polymer solutions, and G_p of the reverse worms formed in oils driven by hydrogen bonding decreases with increasing temperature. In this work, we investigated the reverse worms induced by three chloride salts that bind lecithin through different strengths of electrostatic interactions, in the order of LaCl₃ > CaCl₂ > LiCl. We correlated the interaction strengths with the temperature-dependent rheological properties and found that upon heating, G_p for all the reverse worms driven by electrostatic interactions decays slower than that driven by the weak temperature-sensitive hydrogen bonding. Furthermore, the decay rates of G_p follow an order in the inverse relation to the interaction strength, LaCl₃ ≤ CaCl₂ < LiCl, indicating that the dependence of G_p on temperature can reflect the strength of the driving forces for micellization. We utilized Fourier transform infrared spectroscopy (FTIR) to confirm the weakening of the interaction and the small angle X-ray scattering (SAXS) technique to reveal the decrease in the lengths of the reverse worms as temperature increases, both of which echo the changes in the rheological properties.

无机盐诱导的反蠕状胶束中温度依赖性流变学与静电相互作用的相关性

先前的研究表明，与聚合物溶液相似，由疏水相互作用驱动的水中形成的蠕虫状胶束的平台模量G _p在加热时是一个常数，与氢溶液驱动的油中形成的反向蠕虫的G _p随温度升高而降低。 。在这项工作中，我们研究了由三种氯化物盐（通过LaCl ₃ > CaCl ₂ > LiCl的顺序）通过不同强度的静电相互作用结合卵磷脂的反向蠕虫。我们将相互作用强度与温度相关的流变性质相关联，发现加热后，G _p对于所有由静电相互作用驱动的反向蠕虫，其衰变要比对温度敏感的氢键弱所驱动的蠕变慢。此外，的衰减率ģ _p遵循的顺序在逆相对于相互作用强度，的LaCl ₃ ≤的CaCl ₂ <氯化锂，表明的依赖性ģ _p上温度可以反映驱动力为胶束的强度。我们利用傅立叶变换红外光谱（FTIR）确认了相互作用的减弱，并利用小角X射线散射（SAXS）技术揭示了随着温度的升高，反向蠕虫的长度减少了，这两者都呼应了温度的变化。流变性。
