Mapping Interactions Between Micropatterned Hydrophobic and Hydrophilic Surfaces by Atomic Force Microscopy
Abstract
dc:descriptionHydrophobic and hydrophilic interactions are not additive and the net interactions between heterogeneous surfaces depend on the relative size of hydrophobic and hydrophilic sites on the surface. Independent on whether the hydrophobic sphere is positioned on top of a hydrophobic or hydrophilic area, repulsions are measured, with the same strength and decay length of the electrostatic interaction. Jump into contact distances and adhesion data, between a 20 μm hydrophobic sphere and a heterogeneous surface that has equal hydrophobic and hydrophilic areas will average, whereas in all other cases the hydrophobic sphere will clearly differentiate between the different areas, accurately mapping high and low adhesion areas on the surface.
