Nanotechnology Based Materials
Nano-properties of surfaces inpart determine how fouling organisms adhere and biofouling progresses. This technology is in its infancy but can be used to design new, biocide free surfaces with fouling deterrent and/or fouling release properties. Additionally, nano-particles give a very high surface area and therefore can result in faster and higher affectivity.
Nano/micro topography can be achieved through various methods. A wide range of concepts are covered, including coatings with carefully controlled nano- and micro-structures, polymer based nanocomposites, superhydrophobic/superhydrophilic systems and ‘smart’ or ‘stimulus-responsive’ polymer systems.
Key Factors Positive
- Nanostructuring of a surface coating can control properties such as surface energy, charge, conductivity, porosity, roughness, wettability, friction, physical and chemical reactivity, and compatibility with biological organisms.
Key Factors Negative
- Technology is in its infancy, hence there are a lack of products.
It is very likely, certainly initially, that product cost will be high.
This development could on the long term be delivering the next generation of
