The coating film comprises a liquid crystal (LC) polymer 120 deposited on a flexible sheet 110. The part of the LC layer remote from the flexible sheet has a non-flat surface. The LC polymer is converted from a crystalline phase to a nematic phase and back to a crystalline phase. The coating film 100 is applied onto an object (300, figure 9) when the LC is in the nematic phase, with the LC between the flexible sheet and the object. The nematic LC polymer is cured, preferably be means of electromagnetic radiation. The flexible sheet is preferably a polyethylene terephthalate (PET), polyvinyl alcohol (PVA), polycarbonate or cellulose triacetate film, which preferably has an intrinsic alignment property, enhanced by rubbing. Vacuum degassing is preferably used to remove air bubbles. |
