Transparent hybrid films for stone conservation and protection

Abstract

In this study a silane polymer and an inorganic nanoparticles (TiO2)/polymer composite coating have been tested as protective agents on three different substrates, Carrara/Botticino marbles and Angera stone to improve their hydrophobicity features. The coatings obtained turned out to be hydrophobic as concerns the sylane polymer and superhydrophobic in the case of the hybrid coating. Aging tests have demonstrated the stability of the surface colours.
