Abstract

Any submerged inorganic material is promptly colonized by a variety of microorganisms that offer the basis for the settlement of macroorganisms causing the so-called biofouling. The aim of this work is to evaluate applicability and durability of new designed coatings containing Surface-Active Ionic Liquids for the protection of underwater cultural heritage from the first step of biofouling formation. We report here the results of the characterization test performed on limestone and Carrara marble probes (colorimetric and capillary water absorption measurements) and of the UV weathering to evaluate the durability of these coatings. The results have shown that these coatings do not affect the original properties of the stone surfaces and they are stable over time.
