Aqueous systems dewetting

Whether nudeation or spinodal dewetting dominates the rupture of a liquid film depends on the specific system. The A oc Hq dependence predicted by Eq. (7.34) has been observed in polymer [815, 816, 820] and metal ]821] films. For polymer films in many cases, nudeation is faster [818, 820]. For aqueous films on hydrophobic surfaces, small bubbles are generally accepted to initiate nudeation and nudeation dominates ]813, 814].
