| description | Abstract The surface topographies of natural surfaces play significant roles for improving the ability to adapt to the environment. The micropapilla of lotus leaf is always used to enhance its self‐cleaning performance. However, the function of the submillimeter papilla of lotus has not been well studied. In this study, it is found that the optimal distribution of submillimeter papilla can effectively prevent the rupture of lotus leaf. Under loading, the submillimeter papilla transfers the stress into its root region, which effectively keeps the leaf broadly intact and collaborates to realize relative functions with micropapilla. Further study by integrating the simulations and biofabricated membrane with artificial submillimeter papilla indicates the contribution of submillimeter papilla on the mechanical property. This study opens a novel avenue for designing strength membrane materials, which has potential applications in the fields of soft robot, electronic device, and packaging. |
