A model system was used to study the molecular dynamics and transport of macromolecules, which are very often characterized by their confined state. This complex model consisted of a ternary mixture (reverse micelles) composed of the surfactant sodium bis (2-ethylhexyl) sulfosuccinate (AOT), H₂O and isooctane (C₈H₁₈) as the apolar, oil phase. The dielectric parameters of this system were investigated using the open ended coaxial line method. The high frequency response of the AOT reverse micelles was characterized over a frequency scale from 10 MHz to 20 GHz, as a function of the water-to-surfactant ratio (${\mathrm{W}}_0$) and the surfactant-to-oil ratio (${\mathrm{\Phi }}_{\mathrm{m}}$) at room temperature, 298 K. Measurements of the complex permittivity of this AOT/C₈H₁₈/H₂O system are reported. The experimental values of the real part of the complex permittivity of the AOT reverse micelles were fitted by the Havriliak-Negami function emphasizing the reverse micelles size effect; these measurements were sufficient to give us important information about the dynamic behavior of the AOT reverse micelles dispersed in isooctane. In the frequency range studied three different motions were identified as functions of the reverse micelle size (${\mathrm{R}}_{\mathrm{w}}$).

使用模型系统研究大分子的分子动力学和传输，大分子通常以其受限状态为特征。该复杂模型由三元混合物（反胶束）组成，三元混合物由表面活性剂双（2-乙基己基）磺基琥珀酸钠（AOT），H ₂ O和异辛烷（C ₈ H ₁₈）组成，为非极性油相。使用开放式同轴线方法研究了该系统的介电参数。AOT反胶团的高频响应是在10 MHz至20 GHz的频率范围内表征的，是水与表面活性剂比率的函数（${\mathrm{w\; ^}}_0$）和表面活性剂与油的比例（${\mathrm{\Phi }}_{\mathrm{米}}$）在298 K的室温下进行。报道了该AOT / C ₈ H ₁₈ / H ₂ O系统的复介电常数的测量。通过强调反胶束尺寸效应的Havriliak-Negami函数拟合AOT反胶束的复介电常数的实部的实验值；这些测量结果足以为我们提供有关分散在异辛烷中的AOT反胶束动力学行为的重要信息。在研究的频率范围内，将三种不同的运动确定为反胶束大小的函数（${\mathrm{[R}}_{\mathrm{w}}$）。
