Multifunctional coatings of exfoliated and reassembled graphite on cellulosic substrates.

Exfoliated and reassembled graphite (ERG) forms macroscopic, high aspect ratio (1 : >10) and highly conductive coating layers that are strongly adherent to paper, wood, cloth, ceramic and other substrates. The coating precursor is an aqueous dispersion of graphite that exfoliates spontaneously in alkaline cellulose solutions, forming stable dispersions. These can be applied to the substrates by using different painting, coating and lithography techniques.
