P‐80: Process Optimization of High Hardness Polarizer for Touch Display

In this article, we optimized the preparation process of Hard Coat (HC) materials, studied the influence of UV and postbake parameters on curing rate and film surface warpage, improved the warpage of the film during the curing process, and successfully prepared a high‐hardness HC film that can be applied to touch display. At the same time, by optimizing the pretreatment of the film surface, the adhesion of the Anti‐Fingerprint (AF)material on the HC surface is improved, so that the surface of HC film has no scratches after abrasion test, and the WCA is kept above 110°, which meets requirement the of touch display.
