The technology in a nutshell
  • The process according to the invention allows the graphene layer to be transferred from the source substrate to the target substrate without the use of polymer support coatings.
  • This method guarantees a cleaner surface of graphene and no polymer residue on its surface. In addition, said procedure enables the transfer of the graphene to non-resistant acetone substrates, which is typically used to remove polymers. As a consequence, this significantly increases the possibilities of using graphene. In addition, there is no need for a special holder or any other complicated tools.
  • By applying the method, it is possible to transfer the unlimited shape of the graphene layers even to rough and developed surfaces such as nanowires or materials finished with nanoparticles.

The technology in a nutshell
  • The invention relates to a method of silvering surfaces sensitive to high temperatures, as for example aluminium surfaces, foils, paper or fabric.
  • Presented method provides silvering aluminium surfaces, wherein the sintering stage is performed at temperatures significantly below the aluminium melting temperature, preferably within the range of about 200°C – 400°C, so that the aluminium surface being silvered remains undamaged after the sintering stage.
  • Our method is capable of silvering the surfaces in a simple, rapid, an economical and an environmental friendly manner with high sensitivity and selectivity.

The technology in a nutshell
This invention relates to a method for the preparation of flaked grapevine by direct exfoliation of flake graphite in aqueous solutions. Our method of producing graphene by direct exfoliation of graphite is characterized in that it comprises the following steps:
a) flake graphite is pre-prepared by acid intercalation and thermal expansion, possibly by carrying out these preparatory processes several times;
b) an aqueous slurry of flake graphite with the addition of one or more surfactants is prepared, preparation of the mixture is assisted by treating the mixture with ultrasound, in particular using a probe or an ultrasonic cleaner;
c) the suspension is frozen;
d) the suspension is dried to give graphene.
