Multifunctional coating based on nano fillers and natural substances for ships’ biofouling control
Demands for control and management of ships’ biofouling are pushing development and adoption of new technologies that are cost-effective and more environment-friendly. At the same time, anticorrosion properties and low friction surfaces are required for increasing life time of coating system and fuel saving for applications in the maritime sector. New multifunctional coating system is proposed, matching high-durability together with anti-friction and drag reduction features, combining with antifouling and anticorrosion requirements for the marine industry.
A polymeric infrastructure containing suitably modified nanoparticles is investigated. A layer containing a resin dispersion of functionalised nanoclays is used for corrosion inhibition. An additional layer, suitably adapted to meet synergistic effects with other layers, is used to provide either a durable superhydrophobic coating based on functionalised nanosilicas or for the dispersion of novel ecologically compatible anti-microbial-adhesion- agents, mainly based on natural substances. The final coating system is able to provide high barrier patented features together with low friction properties or with a layer containing enzyme based antifouling active substances, without any additional biocide.
