Ice can be a problem in industrial sectors as wind power, aeronautical and construction, among others. Coatings that allow the reduction of ice formation and which in turn are heated, thereby reducing the icing phenomena, have been developed. The technology consists of transforming a non-conductive polymeric matrix into a heatable material.
The heated surfaces avoid the icing phenomena by keeping the temperature of the coating over 0ºC.
The technology is based on a combination of commercial coatings and carbonous materials with specific fillers in order to allow high degrees of conductivities. For example, heatable coatings can be based on fluorinated polymers and through specific functionalization of CNTs and dispersion, fluorine-fluorine interactions (F-F) are created.
It can be applied as a coating or inner layer by means of spraying or roller techniques. It is also applicable to polyacrylates and polyurethanes with specific functionalizations.
The heatable coating is a low energy consumption system and can reduce the ice formation up to 95%.
In terms of industrial applications, it can be used over the leading edge of UAV systems and wind turbines. The systems can also be set-up over static surfaces such as bridges and building façades.
