Mechanical exfoliation is a method universally used by manufacturers to achieve large-scale production of graphene. In the past two decades, mechanical exfoliation has been a unique enabler of the exploration of emergent 2D materials. Graphene is one type of these materials. With mechanical exfoliation, high-quality two-dimensional graphene materials can be easily obtained and many of them can be typically used to create optoelectronic and electronic devices.
The mechanically exfoliated single crystal graphenes available at Alfa Chemistry include:
Mechanically Exfoliated Single Crystal Graphene on SiO2/Si (SiO2: 300 nm thick)
With SiO2/Si as the substrate and a graphene area exceeding 5000 µm2, Alfa Chemistry offers mechanically exfoliated single crystal graphene in different substrate sizes such as 1 cm x 1 cm, 1.5 cm x 1.5 cm, and 2 cm x 2 cm. It can be applied in or as gas-sensitive materials, electronic displays, composite materials and more.
Mechanically Exfoliated Single Crystal Graphene on SiO2/Si (SiO2: 90 nm thick)
This product is almost the same as the above-mentioned Mechanically Exfoliated Single Crystal Graphene on SiO2/Si (SiO2: 300 nm thick), except that its SiO2 substrate is 90 nm thick.
All graphene products at Alfa Chemistry have undergone strict quality control tests and are widely trusted by universities, research laboratories and high-tech companies worldwide. In addition to mechanically exfoliated crystal graphene, Alfa Chemistry provides a wide variety of other graphene and graphene oxides, including graphene aerogel, graphene dispersion, graphene FET chip, graphene film, graphene nanocomposite, graphene nanomaterials, graphene nanoplatelets, graphene oxide, graphene paper, graphene powder, graphene sheets, reduced graphene oxide, single layer graphene and many more.
About Graphene and Graphene Oxide
Graphene has many advantages such as large theoretical specific surface area, good thermal conductivity and good electrical conductivity, and is hence an exciting material. Graphene oxide is the oxide of graphene, which can be used for applications like hydrogen storage, ion conductors and nanofiltration membranes. As it is fluorescent, graphene oxide is also warmly welcomed in multiple medical scenarios such as bio-sensing, disease detection or serve as drug-carriers or antibacterial materials.
