Polyester Resin and Carbon Nanotubes Based Nanocomposite as New Generation Coating to Prevent Biofilm Formation

In this paper we have developed protective nanocomposite coatings based on unsaturated polyester resin and multi-wall carbon nanotubes showing antimicrobial activity and mechanical durability. Carbon nanotubes retain the mechanical resilience of polyester resin in the nanocomposite, improve its hydrophobic character and increase the adhesion features of the coating preventing its stiffness decrease due to water absorption or to UV rays exposition. The nanocomposite coating exhibits an appreciable antimicrobial property and a lower level of toxicity compared to the pure resin. All these features make this material a good candidate for its use in the field of antibiofilm coatings
