A multi-layer coating with antibacterial and anti-COVID properties which is usable in various environments, including hospitals, and which can be easily deposited by spraying on different surfaces and capable of providing an effective removable barrier against pathogens and bacteria, which waterproof coating is characterized in that it uses graphene nanoparticles as an antibacterial and anti-COVID agent deposited by spraying a polymer material as a host layer on the surface to promote the dispersion and uniform surface distribution thereof, the polymer material being directly adhered by spraying to the surface to be coated or sprayed on a second polymer, in turn sprayed on the surface to be coated, which is used as an element to promote the adhesion of the first polymer forming the antibacterial and anti-COVID coating to the surface to be coated.

Removable, waterproof multi-layer coating having antibacterial properties for contact surfaces and method for the preparation thereof

Disclosed is a dental adhesive including a polymeric adhesive and a nanofiller dispersed in the polymeric adhesive, the nanofiller being constituted by graphene nanostructures which are properly dispersed inside the polymer adhesive and over the surface of the adhesive layer without formation of agglomerates, so that the dental adhesive exhibits significant antimicrobial and antibiofilm properties against pathogens of the oral cavity.

Process for the production of antimicrobial dental adhesives including graphene and relative product thereof
