What are the Methods for Achieving Controllable Adhesion?
Several methods can be employed to achieve controllable adhesion at the nanoscale:
Chemical Modification: By altering the chemical composition of surfaces, specific interactions such as hydrogen bonding, van der Waals forces, or covalent bonding can be tuned. Physical Structuring: Nanostructuring surfaces can lead to changes in surface energy and wettability, which directly impact adhesion. External Stimuli: Applying external stimuli like electric fields, magnetic fields, or temperature changes can dynamically alter adhesive properties.
