Effect of Alcohol-Water Exchange and Surface Scanning on Nanobubbles and the Hydrophobic Force Studied by Atomic Force Microscopy
Atomic force microscopy (AFM) was used to examine how different alcohols affect the hydrophobic attraction between a hydrophobic silica colloidal probe and a hydrophobic silica wafer. The experiments were performed in water and in water after rinsing alcohol (methanol, ethanol or 1-propanol) throughout the AFM system. In all three cases the range of the attractive force increased after alcohol-water exchange, with 1-propanol showing the largest increase
