Revêtements antireflets multifonctionnels par voie sol-gel : application au domaine de l'automobile

Abstract : A multifunctional coating for the automotive industry was elaborated by depositing sol-gel thin films onto glass substrates. Broadband antireflective coatings were synthetized by tuning the optical properties of each deposited layer in order to promote destructive interferences. Different strategies based on a bilayer system and a trilayer system were used to add additional functionalities to the coating. A specific approach was developed to observe fog formation both at the macroscopic scale and at the microscopic scale and therefore to choose the best antifogging coating. These observations were discussed with a modelling method which allows us to compare the macroscopic opacification and the microdroplets populations. Moreover, mechanical tests were performed.
