Abstract
An electrothermal coating can include a nanostructure mixture randomly dispersed in a polymer matrix with more than one type of low-dimensional nanostructure. These types of low-dimensional nanostructures can include a combination of a nanospheroid plus one or both of a linear nanostructure and a planar nanostructure. Useful conductivity is achieved, while concentration of the mixed nanostructures is within the cured polymer composite coating being below the percolation limit of each individual carbon nanostructure type, alone, within an identical polymer matrix.
Claims19
A method of heating a surface comprising:
- applying a coating of a nanostructure mixture randomly dispersed in a polymer matrix to the surface, wherein the nanostructure mixture comprises at least two types of low-dimensional nanostructures, wherein the coating is electrically conductive, and wherein a cured concentration of the nanostructure mixture is below a percolation limit of at least one of the at least two types of low-dimensional nanostructures within the polymer matrix;
- connecting the surface to an electric current power source;
- and
- running the electric current through the coating to heat the surface.
