A novel, functional coating developed by researchers at Battelle may provide a realistic, cost-effective solution. The added functionality of the Battelle coating derives from incorporation of specially formulated, electrically conductive carbon nanotubes (CNTs). Procedures described in early literature generally only produced loadings of 100 ppm. The new three-layer system would replace conventional two-coat systems in use today and includes a primer, the nanotube-containing coating, and a specially designed protective topcoat. The CNT coating system weighs 1/100th as much as current ice-protection systems, and thus would be appropriate for these small aircraft. It also could provide an effective means for improving the performance of wind turbines and preventing icing on commercial aircraft. The researchers at Battelte are excited about the possibilities of the new coating. It also could provide an effective means for improving the performance of wind turbines and preventing icing on commercial aircraft.
