TAIPEI, Nov 30<\/strong> \u2013 Scientists at National Taiwan University have developed a molecular-scale adhesion switch that can make a surface instantly shift from sticky to slippery using electricity.<\/p>\n\n\n\n

The study, published in the Journal of the American Chemical Society<\/em>, shows how applying voltage can control the structuring of ions and water at the boundary between a solid and a liquid. The team used self-assembled monolayers of aromatic molecules on a gold surface to regulate adhesion with mica immersed in a sodium-containing electrolyte.<\/p>\n\n\n\n

By applying negative potential, sodium ions were drawn into the molecular layer, forming a stable cushion-like barrier of ordered ions and water that repelled the mica surface. A positive potential expelled the ions, collapsing the hydration layer and allowing the surfaces to attract.<\/p>\n\n\n\n

Researchers say the electromechanically controlled switch demonstrates how precise manipulation of ions and water at interfaces can create smart, responsive surfaces with tunable mechanical properties.<\/p>\n\n\n\n

\u201cThis system shows a very peculiar mechanism for specific ion structuring and capturing that opens up fascinating new possibilities for understanding and utilizing interface phenomena,\u201d said Prof. Hsiu-Wei Cheng, co-corresponding author of the study.<\/p>\n","protected":false},"excerpt":{"rendered":"
