发明名称 COMPOSITE FILMS SUITABLE FOR USE IN OPTO-ELECTRONIC AND ELECTRONIC DEVICES
摘要 A method of manufacture of a composite film, and a method of manufacturing an electronic or opto-electronic device, said method comprising the steps of (i) forming a polymeric substrate layer; (ii) stretching the substrate layer in at least one direction; (iii) heat-setting under dimensional restraint at a tension in the range of about 19 to about 75 kg/m of film width, at a temperature above the glass transition temperature of the polymer of the substrate layer but below the melting temperature thereof; (iv) heat-stabilising the film at a temperature above the glass transition temperature of the polymer of the substrate layer but below the melting temperature thereof; (v) applying a planarising coating composition such that the surface of said coated substrate exhibits an Ra value of less than 0.6 nm, and/or an Rq value of less than 0.8 nm; and (vi) providing an inorganic barrier layer of thickness from 2 to 1000nm by high-energy vapour deposition; and optionally (vii) providing the composite film comprising said polymeric substrate layer, said planarising coating layer and said inorganic barrier layer as a substrate in said electronic or opto-electronic device; and said composite film and said electronic or opto-electronic device, per se.
