Possibility to granulate nanpowders, like graphene platelets and graphene oxide, achieving granules with high degree of homogeneity which are easily redispersed (if applicable) in a liquid or disintegrated at a pressing operation. This is owing to the soft drying process giving week inter-particle bonding compare to what is obtained in conven­tional drying. Consequently, the nanosized material properties will be preserved, i.e. nano will still be nano. Freeze drying of granules also prevents oxidation of metals or non-oxide materials as conventional drying does not, especially critical for nanoparticles.
