Methods for producing n-doped graphene films are provided. The method includes contacting the graphene layer with an alkali metal doped polymer layer. Also provided are compositions comprising (i) a substrate, (ii) a doped polymer, and (iii) graphene. The methods of the invention produce n-doped graphene films that are resistant to degradation, have high conductivity, and low sheet resistance without altering the light transmittance of the graphene. |
