Graphene

 

Description

Graphene and its derivatives are considered as promising components of electronic devices of a new type of chemical sensors, coatings intendedcomponents for shielding and absorbing electromagnetic radiation and an electrically conductive filler to create conductive coatings, polymer concentrates and compounds.

Graphene nanoplates, modified forms and nanocomposites based on them may be used as additives to polymers, improves their mechanical properties, crack resistance, friction coefficient, wear resistance, UV, heat and flame resistance, electrical and thermal conductivity, as additives in lubricants , electrode materials in chemical current sources, in particular supercapacitors.

Materials based on polyaniline modified GNP may find application in ecology and medicine for adsorption of harmful organic and inorganic substances, neutralization of viruses and bacteria.

Graphene is a crystalline graphite flake diameter of 10 to 100 microns and an average thickness of 3-5 nm. Available as a paste in water or organic solvents with a mass content of 6-10% of nanographite.
