High performance composites and coatings

Composites comprising polyamide-imide and nanoparticles which are also electrically conductive are disclosed. The composites are made by mixing water-based dispersions of nanoparticles, such as graphene which can include hexagonal boron nitride (hBN) with water-based polyamide-imide precursors. Thes...

Zusammenfassung:	Composites comprising polyamide-imide and nanoparticles which are also electrically conductive are disclosed. The composites are made by mixing water-based dispersions of nanoparticles, such as graphene which can include hexagonal boron nitride (hBN) with water-based polyamide-imide precursors. These composites are especially useful as anti-corrosion and anti-wear coatings to protect electrodes in energy storage devices, such as galvanic cell, supercapacitor or a fuel cell, from corrosive electrolytes.
