| 中文摘要 | Surface deformations during the coalescence of two polymer melt films were studied by use of a surface forces apparatus ( SFA). Well-ordered periodic surface ripple/finger patterns were observed during the adhesion and coalescence, which eventually disappeared, leaving smooth polymer-air interfaces. The life-times of these transient well-ordered patterns depend on the viscosity and film thickness of the polymer melts. These observations are in contrast to the conventional understanding that liquid-liquid coalescence usually occurs with the deforming surfaces remaining smoothly curved at all stages, with no esoteric shape-transitions. The results reveal a new feature associated with liquid-liquid adhesion/coalescence, which may be of key importance for a full understanding of coalescence processes. We propose an explanation for the observed phenomenon in terms of simple physical concepts, and discuss other microscopic and macroscopic ( including biological) systems where similar effects are likely to occur. |
