These formulations are capable of replacing the non-ecological antifouling paints currently available on the market. The texture properties and the morphological analysis of these powders with an antifouling action indicate that their activity is linked to the nanometric size of the particles and to the homogeneous dispersion of the metal on the substrate. The presence of two metal species on the same support limits the formation of nanometric species and, therefore, the formation of homogeneous compounds. The presence of the antifouling filler, specifically the one based on titania (TiO2) and silver (Ag), facilitates the achievement of a higher degree of cross-linking of the resin, and therefore, a better compactness and completeness of the coating than that attained with the pure resin. Thus, a high degree of adhesion to the tie-coat and, consequently, to the steel support used for the construction of the boats was achieved in the presence of the silver\u2013titania antifouling.<\/jats:p>","DOI":"10.3390\/polym15112456","type":"journal-article","created":{"date-parts":[[2023,5,26]],"date-time":"2023-05-26T02:00:19Z","timestamp":1685066419000},"page":"2456","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Adhesive and Rheological Features of Ecofriendly Coatings with Antifouling Properties"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5725-9839","authenticated-orcid":false,"given":"Cristina","family":"Scolaro","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Messina, Contrada Di Dio, 98166 Messina, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5442-2469","authenticated-orcid":false,"given":"Leonarda Francesca","family":"Liotta","sequence":"additional","affiliation":[{"name":"Istituto per lo Studio dei Materiali Nanostrutturati (ISMN)-CNR, Via Ugo La Malfa 153, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8348-0764","authenticated-orcid":false,"given":"Carla","family":"Calabrese","sequence":"additional","affiliation":[{"name":"Istituto per lo Studio dei Materiali Nanostrutturati (ISMN)-CNR, Via Ugo La Malfa 153, 90146 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2215-6543","authenticated-orcid":false,"given":"Giuseppe","family":"Marc\u00ec","sequence":"additional","affiliation":[{"name":"\u201cSchiavello-Grillone\u201d Photocatalysis Group, Department of Engineering, University of Palermo, Viale Delle Scienze, 90128 Palermo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1602-9361","authenticated-orcid":false,"given":"Annamaria","family":"Visco","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, Contrada Di Dio, 98166 Messina, Italy"},{"name":"Institute for Polymers, Composites and Biomaterials, CNR-IPCB, Via P.
