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