Improved durability of Bisphenol A polycarbonate by bilayer ceramic nano-coatings alumina-zinc oxide
Abstract Polycarbonate exposed 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 Torque Spanner Set the limit
