Technical Examples
A method of film fabrication is taught that uses a coating and drying apparatus to fabricate resin films suitable for optical applications. In particular, polyvinyl alcohol films are prepared by simultaneous application of multiple liquid layers to a moving carrier substrate. After solvent removal, the polyvinyl alcohol films are peeled from the sacrificial carrier substrate. Polyvinyl alcohol films prepared by the current invention exhibit good dimensional stability and low birefringence.
