摘要

We report observations of a weird but interesting phenomenon from molecular dynamics simulations: the occurrence of second blows in head-on collisions of two equal-sized spherical nano polymer droplets. In head-on collisions, we usually expect single-peak impact forces between the two colliding droplets. However, a second peak of the impact force is actually observed in the simulations. Its underlying mechanisms on a molecular scale are proposed.
