摘要

本研究探讨了 DMSO 在六方介相的 Triton X 和水二元体系中的作用。通过偏振光学显微镜和小角 X 射线散射测量确定了 DMSO 添加的一个作用，即促进六方相向各向同性相转变温度 TH-ISO 的降低，减小六方相的温度范围，直到 DMSO 添加量达到 5.0 mol % 时六方相完全消失。作为 DMSO 浓度的函数计算出的六方排列的周期性和晶格参数略有增加，这是由于 DMSO 分子插入了水区，导致圆柱形胶束之间的距离增大，而极性域的半径则保持在 22 (1) Å。

Effect of DMSO Addition on the Hexagonal Phase of the System Triton X/Water.

This research studied the role of DMSO in a binary system of Triton X and water in the hexagonal mesophase. One effect of DMSO addition, determined using polarized optical microscopy and small-angle X-ray scattering measurements, is to promote a decrease in the hexagonal to isotropic phase transition temperature, T_H-ISO, decreasing the range of temperatures of the hexagonal phase until the hexagonal phase completely disappears when DMSO is added up to 5.0 mol %. The periodicity and the lattice parameter of the hexagonal arrangement, calculated as a function of DMSO concentration, slight increased due to the insertion of DMSO molecules in the water region, causing a greater distance between the cylindrical micelles, while the radius of the apolar domains kept constant at 22 (1) Å.
