On one hand, it is important to take into account the antibacterial activity of the polymeric films, but on the other hand, it is equally essential to obtain appropriate surface proper- ties in order to make it less susceptible to bacterial attachment and biofilm maturation. Within this framework, the incorporation of citronellol and eugenol makes the surface hostile to the bacterial adhesion. The primary attachment to surfaces is a crucial event for the biofilm formation, and it depends on factors such as the physicochemical properties of substratum surfaces, bacterial characteristics, and environmental components.
