Mechanical Exfoliation

Mechanical Exfoliation Graphene 24 April 2020


The mechanical exfoliation method was first described in 2008. It was in response to the need for a scalable production method for graphene. Mechanical exfoliation is a top-down approach that requires mechanical energy in order to exfoliate graphite.

Graphene is a hydrophobic material, which is why additives or surfactants are required in order to obtain stable dispersions in polar solvents. Furthermore, many of the surfactants or organic solvents used can be toxic or otherwise harmful.

Although this production method is simple enough, the quality and purity of the exfoliated graphene may not be sufficient for specific applications.

Is graphene toxic to human health?

Graphene was discovered relatively recently. While everyone agrees on its incredible properties and the possibilities it brings to industry in particular, more and more studies are also aiming to assess graphene’s toxicity on human health. This issue is attracting growing interest, including from the general public, particularly since the health crisis of 2020-2021, when graphene-based […]
