G-GOSiO

Large graphene oxide (GO) sheets supported on Si oxide.

Graphene oxide (GO) sheets produced through chemical graphite exfoliation, supported on silicon oxide substrate, 300 nm. Thanks to the large dimension of each single layer of GO, up to 150 µm, this product can meet the highest researchers’ requirements.

GO platelets can be easily identified with an optical microscope when deposited on silicon oxide substrate, similarly to mechanically exfoliated graphene.

Though, their high and uniform density on the substrate (and the absence of large agglomerates and debris, typical of mechanically exfoliated graphene) make G-GOSiO the perfect substrate for quick and efficient research applications.

Sample reduction of GO can be done either chemically or by thermal treatment.

GOSi

Graphene oxide (GO) sheets supported on silicon.

Small to medium size graphene oxide (GO) sheets produced through chemical graphite exfoliation, supported on silicon. Typical sheets have lateral dimension in the range of 1-10 µm; samples with different area coverage are available to meet your needs.
