<p>A layer 6 comprising a polymer such as polyethylene terphthalate (PET) in an amorphous form is deposited on a surface 4 of a substrate 1 comprising a polymer such as PET. The amorphous layer 6 improves the surface properties of the substrate 1, for example by assisting the deposition of further layers. The amorphous layer 6 is deposited using a method in which a solution of PET is deposited on the surface 4 of the substrate 1 which is moved, e.g., by rotation, at a speed sufficient to spread the solution and evaporate the solvent. <IMAGE></p> |
