In fact, graphene is originally present in nature. However, its monolayer structure made it difficult to be peeled off.
In 2004, two scientists Andre Geim and Konstantin Novoselov at the University of Manchester, England first peeled off raphite sheet from graphite, and then stuck the two sides of the sheet on a special tape. They then successfully tore tlape and dividing the graphite sheet into two. By repeatedly doing this, they have made the sheet thinner and thinner. Finaly, they got the results they have wanted
Biomass graphene: Beside thermal conductivity, It has good properties such as conductivity and magnetism of
graphene.It also has the unique property of super-strong adsorption,far infrared emission,highly efficient in antibac-
terial function.It can generate negative ions and has other characteristics.
