What is the transmittance of graphene aerogels?

The transmittance of graphene aerogels is 97.7%. Graphene has a thermal conductivity as high as 5×103MW-1k-1and a light transmittance of 97.7%, which also shows extraordinary characteristics in antibacterial and barrier properties. Graphene is a single-layer graphite with sp2 carbon atoms arranged in a hexagonal array, which has a high internal carrier mobility (200,000 cm2v-1s).
