Published by Elsevier B.V. Peer-review under responsibility of the 6th International Conference “Fracture Mechanics of Materials and Structural Integrity” organizers Paper presents the results of wettability measurements of water and acrylic resin on flat surfaces with deposited GO. The substrate for GO deposition was plasma cleaned constructive steel S235 and laboratory glass. Obtained results were compared to surfaces without GO deposition. Additionally, wettability experiments were carried out on steel S235 with corrosive surface. Examined surfaces were characterized with structural and FTIR analysis. As a result surface roughness of all examined surfaces changed after GO deposition. The results showed that highest hydrophobicity was registered for glass surface with deposited GO. Water contact angle increased on steel + GO S235 and glass + GO about 25 and 411% respectively as compared to un-deposited surfaces. No changes were recorded for contact angle of acrylic resin on steel S235 deposited with GO as compared to un deposited, 10% increase was recorded for glass + GO surface.
