摘要:

采用悬滴法通过对界面面积变化及动态界面张力变化的测试,研究脂肽复配型弱碱三元复合驱界面张力以及扩张模量随时间、浓度的变化,并采用SPSS软件对实验数据进行非线性拟合,得到三因素的扩张模量预测模型,分析界面流变性质。该实验操作简单,实验体系设计灵活,同时与油田现场科研项目联系紧密,不仅丰富了物理化学实验有关界面化学实验课程设计,还可以引导学生关注实际生产,激发学生学习兴趣,训练学生软件应用能力及数据分析能力,符合应用型本科培养要求。通过科教融合的培养模式,提升学生处理实际问题的综合能力。

Abstract:

In this experiment, the changes in the interfacial area and dynamic interfacial tension were measured using a hanging drop method, and the changes in the interfacial tension and expansion modulus with time and concentration were investigated. SPSS software was used to fit the experimental data non-linearly. A three-factor prediction model of the expansion modulus was obtained and the rheological properties of the interface were analyzed. The experiment is simple to perform, has a flexible system design, and is closely related to research projects in this field. It not only enriches the curriculum design of the interface chemistry experiment, but also guides students to pay attention to the actual production, stimulating the students interest for learning, and develops student software application and data analysis abilities, meeting the requirements of application-oriented undergraduate education. This types of a training mode involving the integration of science and education is expected to improve the student ability to deal with practical problems.

Key words: Interfacial rheology, Lipopeptide complex, Dilatation modulus, Physical chemistry experiments
