Transparent Hybrid Films for Stone Conservation and Protection

2014
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
