Marine bio-incrustation is produced by the adhesion of microorganisms at
artificial surface in contact with seawater. These incrustations are related with
the natural marine process and they can generate negative ecological,
economical and healthcare effects. Common toxic additives in paints have been
used to avoid the algae adhesion produced by bacterial biofilms, considering
that environment contamination is still present. However, recent advances in
antifouling coatings design involves the use of nanomaterials to produce multifunctional
properties as antimicrobial/UV stability and corrosion resistance. The
present work proposes the preparation of polymer nanocomposites based on
acrylic/Cu/ZnO nanoparticles by means of ultrasound assisted method,
correlating their physicochemical and antibacterial characteristics. Our results
suggest the homogenous dispersion of NPs in polymer matrix and antimicrobial
activity in contact with common pathogens, avoid the biofilm formation. This
activity was highly influenced by the nanoparticles concentration. The design of
functional and nontoxic antifouling coatings has been an important issue in the
manufacture of boat coating paints and ocean energy technologies for
renewable energy generation.
