What are the Key Mechanisms Behind Nanotechnology-Enabled Adhesives?
Several mechanisms contribute to the performance of nanotechnology-enabled reusable adhesives: 1. Van der Waals Forces: By creating a high density of nanoscale contact points, these adhesives maximize Van der Waals forces, which are weak intermolecular attractions that provide significant adhesion. 2. Capillary Forces: Some reusable adhesives utilize nanoscale features to trap minuscule amounts of liquid, enhancing adhesion through capillary action. 3. Mechanical Interlocking: Nanoscale hooks or loops can create a mechanical bond with the surface, providing strong yet reversible adhesion.
