摘要:

两种不相容聚合物界面张力的测量多集中在理论和实验层面，缺少适用于工程应用系统设计的数值模拟方法。通过椭球液滴回缩法测量了聚苯乙烯（PS）与茂金属催化的乙烯-辛稀共聚物（POE）之间的界面张力，并运用数值模拟软件中的非牛顿流体模型对实验过程进行仿真，验证两种方法测量界面张力的吻合性。在此基础上，考察了同一聚合物体系下分散相与连续相的黏度比对界面张力的影响。结果表明，数值模拟方法测量界面张力与实验数据吻合较好，说明了该方法的可靠性。PS/POE体系在230 ℃下的界面张力值为0.397 mN/m，同时，聚合物系统的黏度比对界面张力有显著正影响。

Abstract:

Measurement of interfacial tension of two incompatible polymers mainly focuses on the theoretical and experimental level，and lacks numerical simulation method suitable for the design of engineering application system. In this paper，the interfacial tension between polystyrene （PS） and metallocene catalyzed polymers of ethylene and octene （POE） was measured by an ellipsoidal droplet retracting method，and the experimental process was simulated by a non-Newtonian fluid model in a numerical simulation software to verify the coincidence of the two methods in measuring interfacial tension. On this basis，the influence of different viscosity ratios of dispersed phase and continuous phase on interfacial tension in the same polymer system was investigated. The results show that the numerical simulation method is in good agreement with the experimental data，which indicates the reliability of the method. The interfacial tension of PS/POE system is 0.397 mN/m at 230 ℃，and the viscosity ratio of polymer system has a significant positive effect on the interfacial tension.
