液滴撞击固体基底现象广泛存在于自然界、日常生活及工业生产中.在多数液滴撞击场景中,固体基底可以近似地视为理想刚性基底.然而在一些场景中,具有较小杨氏模量或者几何结构为薄壁或细长类的固体基底在受到液滴撞击后会产生明显的变形,而固体基底的形变反过来又会影响液滴的动力学行为.相比于刚性基底情况,液滴与柔性基底的耦合作用可能会引发新的动力学现象和机制.因此,柔性基底液滴撞击动力学的研究很有意义,也成为一些学者当前关注的研究焦点之一.根据几何结构的特点,柔性基底可以分为柔性体、柔性面和柔性杆3种类型.文章据此分类介绍与这3类柔性基底相关的液滴撞击动力学的研究进展.柔性基底的可变形性是导致其液滴动力学与刚性基底液滴动力学存在差异的根本原因.现有的研究表明,基底柔性对液滴撞击的接触时间、最大铺展因子、气泡捕获、回弹和溅射等方面均存在着影响,其中关于接触时间及溅射方面的结论可能为制造防水、抗冰和防溅射材料提供新思路.
