Surface rearrangement of water-immersed hydrophobic solids by gaseous nanobubbles

Popis výsledku v původním jazyce

Interactions of gaseous (ambient) nanobubbles (10-100 nm diameter) with different hydrophobic materials - Teflon, polystyrene, paraffin, and basal plane highly ordered pyrolytic graphite (HOPG) - are studied by AFM in situ and ex situ. Exactly identicalsurface locations are examined before and after exposure to ambient gas nanobubbles in deionized water and compared for nanomorphological changes. While freely flooded/immersed surfaces, regularly occupied by nanobubbles, do not exhibit resolvable alterations, significant surface rearrangement is found on whole flooded area after mild pressure drop (10 kPa) applied on the solid-liquid interface. Nanopattern and its characteristic dimension appear to be material specific and solely reflect surface-nanobubble interaction. Mild, nonswelling, noncorrosive conditions (20°C, deionized water) prevent intervention of chemical reaction and high-energy-demanding processes. Experimental results, in accordance with the presented model, indicate tha
