Abstract
Microbubble(MB) can be applied for cleaning of hydrophobic compounds on substrates. To characterize interaction between MB and the comounds, we observed surface of casted hydrophobic ink on glass, and surveyed loss of weight after cleaning using MB generating device by hydrogen bubble method and a microscope. The observed images on the ink after cleaning show the decrease in number of the holes generated by adsorption of MBs on the substrate decreased and the increase in diameter of the holes becaseue of increasing diameter of MB as the surface of the ink was distant from the electrode. We found a significant difference between the removals of the ink weights at the distance of 10 mm and 40 mm. These results suggested that the efficiency of cleaning of the hydropobic ink increased by generating MBs with diameter of 10 μm.
