Abstract
A method for preparing a flexible film substrate with a low glass transition temperature can be used in the production of an article that retains dimensions and improves the surface smoothness after high temperature processing. The invention, for example, would enable low temperature films such as PET and PEN to be dimensionally stable and ultra flat at conditions commonly used in electronic processing which can typically exceed 200° C. More specifically, the methods enable the use of e.g. barrier films based on PET or PEN in OLED/PLED manufacturing.
