Nanoparticles of a number of inorganic compounds have been shown to possess anti-bacterial and anti-viral properties. The objective of the project was to produce an antiviral surface coating of these particles that could be used in applications such as air filtration and surfaces likely to act as vectors in the transmission of viral and bacterial infections. The main requirement for the coating was that the particles had to be completely exposed to the surrounding air. This raised the problem of bonding the particles to the surface without any encapsulation. The coatings were prepared by electrophoretic deposition and dipping from liquid suspensions of the nanoparticles. Several post coating treatments were applied to improve the bonding of the particles to the substrate. Nanoscratch testing has been used to measure the adhesion force between the coating and the substrate and SEM to characterise the coatings and scratch tracks.
