摘要
En 中文
Inspired by nature, structured interfaces have been shown to enhance adhesion by trapping crack propagation along the interface. In many applications, directional adhesion is desired where interface separation along different directions requires different fracture energy. In this work, we numerically investigate a strategy to attain enhanced and directional adhesion using an interface that contains asymmetric complementary patterns. Finite element analyses were performed to calculate the energy release rate at different crack lengths on the patterned interface, and the results were compared to those for a flat control. Our results show that the adhesion is stronger on the patterned interface and the adhesion enhancement is greater along one direction than the other, suggesting directional adhesion. Different degrees of directional adhesion can be achieved by modulating the aspect ratio of the pattern on the interface without modifying surface chemistry, which bears great potential in applications where different levels of adhesion and directional adhesion are desired for different purposes.
