- W2171313490 abstract "Polymers, or macromolecules, dominate today’s materials industry and play key roles in many areas of science and technology. The behavior of polymers at surfaces and interfaces has proved to be an important factor in understanding wetting issues, because the morphological features of a polymer film on a solid surface depend on the nature of interactions between the polymer and the solid. Ultrathin films are unstable and break spontaneously via a spinodal mechanism or by heterogeneous hole nucleations. In contrast, macroscopic films are stable. With the help of electric fields and temperature gradients, a destabilizing interfacial pressure can be generated at their surface. If the external pressure overcome the stabilizing effect of the surface tension, it drives the film towards dewetting. The external, either electric or thermic field, can be applied by placing the polymer film between two electrodes in a capacitor geometry, including also an air gap. The developing morphology can be controlled by laterally varying the applied fields with the help of a structured electrode. As a consequence, the instability is driven towards the regions with high field intensity. However, the interaction of the external fields with the polymer film is undesired when using an electrically active polymeric material. This limitation may be circumvented by making use of film instabilities that are intrinsic to the system. In case of a film made of a polymer blend, its surface can become spontaneously unstable due to surface tension gradients at film–air interface. If confined by a topographically structured surface, the undulatory mode of the film instability is harnessed to induce directionality and functionality to the film. Polymer blends are also of practical interest as a means of obtaining micro– structured materials. We present a method of obtaining porous materials based on demixing of a polymer blend followed by a subsequent washing of one of the polymers. If the phase morphology has a lateral length scale below 100 nm, the resulting nanoporous films can be used as high performance antireflection coatings. In conclusion, nanoscale materials and processes have potential applications in many areas such as biological detection, controlled drug delivery, optical devices, sensors, etc. The advancement of new methods to control the pattern formation processes gives us the possibility to develop functional materials that improve the technical inventory of our modern life." @default.
