Dewetting and pattern formation in thin polymer films as investigated in real and reciprocal space

The dewetting of thin polymer films and the resulting pattern formation are reviewed and previewed. Being of crucial importance for various applications, the destabilization of an initially homogeneous layer has been investigated intensively. Recently, the growing complexity of the systems under investigation introduced new questions. In this highly active research area, different complementary methods such as experiments, computer simulations and theory have yielded new insights. Particular emphasis is placed on experiments. Future perspectives are discussed in addition.
