在Weeks-Chandler-Andersen(WCA)微扰理论的基础上,建立了一个状态方程,研究了温度和压力以及模型共聚物分子链长对体系相平衡和临界胶束浓度的影响.
In this work, an equation of state based on the Weeks-Chandler-Andersen (WCA) perturbation theory was established for the mixture of SC-CO2 and model copolymer. The influences of temperature, pressure and chain length of model copolymer molecules on phase equilibria and critical micelle concentration (CMC) were investigated.
