A preferably aqueous dispersion comprises carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from &#x2267;5:95 to &#x2266;75:25. In a process for preparing a dispersion of this kind, carbon nanotubes and graphene platelets are combined so that the ratio by mass of carbon nanotubes to graphene platelets in the dispersion is in a range from &#x2267;5:95 to &#x2266;75:25. The dispersion can be used as a printing ink for producing electrically conductive films. The invention further provides an electrically conductive film comprising carbon nanotubes and graphene platelets, with the ratio by mass of carbon nanotubes to graphene platelets being situated within a range from &#x2267;5:95 to &#x2266;75:25.

Dispersion comprising carbon nanotubes and graphene platelets

Process for the preparation of stable suspensions and dispersions of carbon nanotubes, and dispersions prepared by the process.

Production of dispersions containing carbon nanotubes

The present invention relates to a process which comprises: providing a substrate having a surface; applying a dispersion to the surface, wherein the dispersion comprises at least one liquid dispersant, and electrostatically stabilized silver nanoparticles having a zeta potential of from &#x2212;20 to &#x2212;55 mV in the dispersant at a pH value of from 2 to 10; and heating one or both of the surface and the dispersion applied thereon to a temperature of from 50&#xb0; C. below the boiling point of the dispersant to 150&#xb0; C. above the boiling point of the dispersant, to form a conductive coating on the surface.

Production of conductive surface coatings using a dispersion containing electrostatically stabilised silver nanoparticles

The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.
