Capillary adhesion in micro-nano technology is significantly influential and can be weakened or eliminated by optimizing shapes through dissolution. This study demonstrates that dissolution optimizes the adhesion force and sculpts unique geometrical shapes that effectively eliminate capillary adhesion. The mechanism of elimination is related to the stability of menisci around the optimized shapes, and the surface roughness of soluble fibers highlights the role of contact angle hysteresis (CAH) in the process. This research provides a promising approach to eliminate capillary adhesion by designing geometrical shapes.
Capillary adhesion is so remarkable in micro-nano technology that it can seriously influence accuracy and safety. The shapes optimized by dissolution provide a method to weaken or even eliminate capillary adhesion. Based on the dissolution experiments of soluble fibers, this work demonstrates that the process of dissolution is an optimization of the adhesion force, and the unique geometrical shapes sculpted by dissolution can effectively eliminate capillary adhesion. The mechanism of elimination is relevant to the stability of menisci around the optimized shapes. The surface roughness of soluble fibers is considered to emphasize the significant role of contact angle hysteresis (CAH), and the shapes optimized by dissolution with CAH are in great agreement with the experiment results. This study supplies a promising approach to eliminate capillary adhesion by designing geometrical shapes.
