The field of biomimetics is expanding in engineering and refers to the mimicking of natural system functionality in technological systems. The most well known example of biomimetics is the development of Velcro which resulted from the inability of burrs from bushes to be removed from the fur of a dog. Biomimetics in surface engineering is also receiving attention as nature provides surfaces with a whole range of functionality. This is often achieved by nanostructuring at different length scales. This work is an initial study of some nanostructured polymer surfaces, derived from the anti-reflective moth-eye structure as surfaces to reduce mineral scale deposition. The study has shown that compared to stainless steel the polymer surfaces all reduce scale deposition and also within the polymers there is a range of behaviour. Some initial suggestions of the controlling factors in deposition on these systems are discussed.
