Abstract
A method of forming a liquid crystal polymer layer includes: coating a substrate with a release layer; coating the release layer with an alignment layer capable of aligning a liquid crystal polymer layer; coating the alignment layer with a layer of a liquid crystal polymer material, thereby forming a liquid crystal polymer layer in which the molecules have a predetermined orientation; solidifying the layer of liquid crystal polymer; and dissolving the release layer in a liquid which does not harm the solidified liquid crystal polymer layer to form a self supporting film. The release layer and alignment layer can be combined into a single layer, such as for example a layer of polyvinyl alcohol which may be dissolved in water. Thicker or multi-layer films can be fabricated by using the first solidified layer as an alignment layer for a subsequently deposited liquid crystal polymer layer.
