Abstract
The purpose of this project is focused on the synthesis and characterization of photochromic organic-inorganic hybrid (HOI) materials containing tungsten (PWA) and molybdenum polyoxometalates (PMo) by sol gel process on polyethylene terephtalate (PET) flexible substrate by using inkjet technique. Hybrids so-called di and tri-ureasils containing different polymer chain length and concentra…
