This work focuses on the design of bulk nanomaterials for ice protection in various applications, using the heating effect produced by dispersed electrically conductive nanoparticles. The effectiveness of Joule heating was evaluated for a resin with low viscosity, containing carbon nanotubes and expanded graphite. Nanocomposites with expanded graphite showed better heating efficiency and lower viscosity, making them advantageous for practical applications.
This work deals with the design of bulk nanomaterials able to provide ice protection in different applications ranging from civil to aerospace and automotive engineering. Bulk nanomaterials containing dispersed electrically conductive nanoparticles have been formulated. The heating performed through the Joule effect represents an efficient strategy to rapidly contrast extreme cold and humidity conditions, to reduce environmental pollution and to control rheological properties during the process. The effectiveness of the Joule effect has been evaluated for the same resin, characterized by low values of viscosity, containing incorporated carbon nanotubes and two different grades of expanded graphite. The comparison among the chosen fillers highlights that the nanocomposite containing incorporated the unidimensional filler reaches higher temperatures for lower values of the applied voltage. Graphite nanoplatelets can be advantageously used to reduce the viscosity of the nanomaterials. A higher expansion of the graphite allows for obtaining better performance in the heating efficiency.
