High Throughput Preparation of Large Area Transparent Electrodes Using Non-Functionalized Graphene Nanoribbons

Transparent conducting films were prepared by using non-functionalized, non-oxidized graphene nanoribbons. Two different dispersion methods were compared. The produced films show sheet resistance as low as 800 Ω/sq when the transmittance at 550 nm is 78%. The performance of the films were close to the entry level for transparent electrode applications and is comparable to those of graphitized chemically converted graphene films, but in this case, no high temperature annealing step was required, thereby rendering this a technique suitable for use on thermally sensitive materials.
