摘要
采用分子动力学模拟技术,对C_(12)E_2-正十二烷-水体系的界面行为进行了研究。模拟结果表明:C_(12)E_2-正十二烷-水体系的界面厚度随温度的升高而产生较大的起伏;在343 K时,界面厚度出现最大值。C_(12)E_2-正十二烷-水体系的界面张力随温度的提高而出现较大的波动;在343 K时,界面张力出现最小值。
Interface behaviors for the system of lauryl alcohol ethoxylates（C12E2） and n-dodecane and water are studied by molecular dynamics（ MD） simulation. The simulation results suggest that interface thickness of the C12E2-n-dodecane-water system fluctuates obviously as temperature rises,and the maximum value is arised at 343 K. The interface tension of the C12E2-n-dodecane-water system varies with temperature strongly and the greater fluctuation of the temperature,and the minimum value is arised at 343 K.
