Abstract

The film consists of one or more Langmuir-Blodgett layers, the layer containing an organic polymer having long-chain fluoroalkyl side groups or consisting of this compound. The film is distinguished by a multilayer structure having few defects and is, for example, suitable for optical purposes and for surface treatment. The order of the molecules in the multilayer can be improved by annealing and by heating the film through the phase transition and cooling again.
