Water adhesion-tunable film prepared with morphology-controllable core/shell particles

Here, we report a surface-mediated buckling process via thermal annealing for fabricating morphology-controllable particles. We obtained both dimple-like particles and backrest chair-like particles, and the indentation depth of these particles could be tuned. Furthermore, we successfully utilized the core/shell particles to build water adhesion-tunable films. These films could potentially be used as transfer-printing materials.
