A number of instabilities that exist in solid and liquid polymeric films of micro and nano scales are studied. The first group of instabilities are associates with thin polymer films on nonwettable substrates, which can become unstable and make rupture in the form of creating a series of patterns reflecting fluctuations in local film thickness or defects. Understanding the stability, dynamics and morphology of polymer films has attracted much attention because systems appear in various products and processes ranging from coating, adhesives, flotation, and biological membranes to a host of areas in nanotechnology. The other group to be discussed is related to interfacial corrugations in electrokinetic flow of thin polymeric liquids. Mechanism of these instabilities will be explained with subsequent remarks on their critical applications. |
