Graphene dispersions easily form micron-thick highly conductive films on most substrates including paper, glass, plastic films and cartons.
Films made from this dispersion require 30 minutes of drying time at room temperature.
Such films can be deposited by blade or bar coating. These films have a smooth, paper-like structure.

Though films are conductive as deposited, conductivity may be improved by gentle annealing in air at temperatures which do not exceed 350 °C. After annealing, values will be in the range of 10-20 Ohms/□ at 25 micron film thickness. This value is given as an example, the actual value will depend upon deposition method and the target substrate.
Applications:
An additive to polymers, graphene-based composites
Thermally conductive compounds
Inks and coatings
Heat sinks
Electromagnetic Interference Shielding
Thin film batteries
Antistatic films
