General description

  • Form: Brown/Black powder
  • Bulk Density: ~1.8 g/cm3
  • Solubility: Dispersible in water and polar solvents
  • Number of layers: 15-20
  • Oxidation: 4-10%
The material basically consists of exfoliated graphene nanoplatelets containing functional organic groups. The oxygen content is less than 5%; the majority groups are hydroxyls (OH), which enables further chemical modifications to add new functionalities. The functionalization approach was designed to attach most of the groups on the border of the foils, aiming to preserve the intrinsic properties of graphene (e.g.: electric conductivity).

Application

The product is aimed for dispersion and/or incorporation in polar solvents (e.g.: water, THF and DMF) and polar polymeric matrices (e.g.: PLA, PA and PET). It is suitable for in situ polymerization, direct resin mixing and molding, solvent dissolution, extrusion processing after incorporation. Potential applications include:
  • Nanocomposites [1,2]
  • Anti-corrosion coatings [3,4]
  • Films with barrier properties [5,6]
  • Membranes for separation [7,8]
  • Conductive inks [9,10]
  • Energy storage [11,12]
