Graphene materials for coatings

Thursday, 12 July 2012 | Posted by: Prof. Rigoberto Advincula, Case Western Reserve University

Electrically conducting coatings, barrier materials, transparent electrodes, pressure sensitive coatings, sensing coatings (stimuli responsive), and anti-corrosion coatings.

Graphene is an allotropic form of carbon which have been formed from the exfoliation of graphite or can be prepared by deposition methods under high vacuum, plasma conditions, or chemical vapor deposition. The subject of the Nobel prize winners in 2010, these materials have gone the route of carbon nanotubes and bucky balls in that they have been widely accepted to be the best new thing in polymer nanocomposites. The advantages: relatively cheap source (graphite), can be made soluble or a suspension, can be exfoliated to form nanosheets, and a host of interesting properties not found in other nanofiller materials. These salient properties include: conductivity, very high aspect ratio, chemical resistivity, high organic functionality in the oxide form, etc. The high solubility especially of the graphene oxide form should make it readily available for mixing formulations. Possible uses for coatings: electrically conducting coatings, barrier materials, transparent electrodes, pressure sensitive coatings, sensing coatings (stimuli responsive), and anti-corrosion coatings.
