Understanding the interfacial properties of solids with their environment is a crucial problem in fundamental science and applications. Elastomers have challenged the scientific community in this respect, and a satisfying description is still missing. Here, we argue that the interfacial properties of elastomers, such as their wettability, can be understood with a nonlinear elastic model with the assumption of a strain-independent surface energy. We show that our model captures accurately available data on elastomer wettability and discuss its implications.
了解固体与其环境的界面特性是基础科学和应用中的一个关键问题。在这方面,弹性体给科学界带来了挑战,目前仍缺乏令人满意的描述。在此,我们认为,在假设表面能与应变无关的情况下,弹性体的界面特性,如润湿性,可以用非线性弹性模型来理解。我们表明,我们的模型准确地捕捉了弹性体润湿性的现有数据,并讨论了其意义。
