▎ 摘　　要

NOVELTY - A platelet comprises a graphene layer and protein layer on the surface of the graphene layer. USE - In electronic device (claimed). ADVANTAGE - The method facilitate exfoliation of graphene to the extent that it is possible to perform exfoliation even at temperatures below 100 degrees C. Thus, a higher quality of the produced graphene is achieved that by the methods using high temperatures, as in high temperatures the graphene is vulnerable to oxidation or other damage. Lower temperatures are also safer for the operator personnel and do not set so strict requirements for the design of the production equipment. The nano-scaled platelets are used as filler components in nanocomposite materials, the cost of the filler can be a very important factor. The method is efficient in energy, i.e. that the process does not require high temperatures or input of energy; is carried out using solvents such as water, thus reducing environmental burden and decreasing costs. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) producing (M1) graphene-containing platelets involving: facilitating exfoliation of a graphene layer from a surface by treatment with proteins; and (2) an electronic device comprises the platelet.
