Improved durability of Bisphenol A polycarbonate by bilayer ceramic nano-coatings alumina-zinc oxide
Abstract Polycarbonate exposed diet frostie root beer to sunlight yellows, degrades and loses its usable properties.In order to increase its lifetime, it can be coated with nano-ceramic thin layers of ZnO and Al2O3 deposited by sputtering.The role of the ZnO is to absorb the UV photons that can damageable for the polycarbonate.However, one of the l
