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