The sticky problem is still a challenge when preparing the high-quality membrane without UV curing process. Therefore, this present work intends to adopt different types of additives to solve the sticky problem. The result of anti-sticky test reveals that the addition of silica nanopowders is capable of improving the membrane performance, confirmed by the. The modified membrane also exhibits excellent extension performance after the post-UV curing, confirmed by the Instron test, pencil hardness test, and RCA measurement. As a result, the addition of silica could also improve the transfer process. On the basis of the results, the silica addition not only raises the hardness but also promotes the wear resistance via the post-UV curing process.
