Sapphire thin film coated flexible substrate
Sapphire thin film coated flexible substrate
A method to transfer a layer of harder thin film substrate onto a softer, flexible substrate. In particular, the present invention provides a method to deposit a layer of sapphire thin film on to a softer and flexible substrate e.g. PET, polymers, plastics, paper and fabrics. This combination provides the hardness of sapphire thin film to softer flexible substrates.
Less fragile, have good mechanical performance and cost less.
