Abstract

Bio-based networks derived from eugenol were prepared with an eco-friendly process by photoactivated thiol-ene reactions. Allyl derivative eugenol, prepared by a nucleophilic substitution was combined with linalool, a monoterpene present in the lavender essential oil, well known for its antibacterial activity, with eugenol, or carvacrol, sustainable antioxidant molecule components of the essential oil of clove and oil of thyme, respectively. The photoactivated thiol-ene reaction is a quick room temperature straightforward way to obtain renewable cross-linked networks. Several systems have been developed including, covalent grafting of linalool, eugenol, or inclusion of carvacrol moieties to obtain functional materials. Two bacteria strains were used in vitro to evaluate the resistance to bacterial adhesion and the DPPH method was used to determine the antioxidant properties of the networks. As expected, the results showed a strong anti-adhesion activity against S. aureus and E. coli due to the presence of eugenol moieties and carvacrol release. Moreover, the phenol groups of grafted eugenol or free carvacrol provide an antioxidant activity characterized by a radical scavenging activity higher than 90%.
