Industrial Scale Production of CVD Graphene

Key Challenges:

Transfer on insulators
Production cost
Reduced conductance

Transmittance and sheet resistance data for papers appearing in the literature. These are broken down into films prepared by CVD,

r from reduced graphene oxide or

chemically modified graphene, pristine exfoliated graphene, or chemically synthesized graphene. In all cases the data in the figure correspond to the best data reported.

Sukanta De and Jonathan N. Coleman ACS Nano, 2010, 4 (5), pp 2713–2720

Targeted Markets:

Displays, touch panels
Solar Cells
Flexible Electronics
Transparent Conductors
