Typical CCD images of the test sample surface in the temporal lowering of hydrophobicity. The change of hydrophobicity can be classified into three phases. (a) First phase of temporal lowering of hydrophobicity. (b) Second phase of temporal lowering of hydrophobicity. (c) Final phase of temporal lowering of hydrophobicity.
