Robustness tests of biomimetic materials. This movie includes two parts: 1, the test using a buckling device; 2, liquid droplets bouncing on the biomimetic materials during the 105-times buckling. The surface-engineered polymer membrane nicely maintained the repellence to water after 105-times of buckling tests.
