Size reduction and polymer encapsulation of carbon black in gas-expanded solvents
… in CO₂-expanded acetone and produces colloidal carbon black particles. These particles should be uniformly coated with functionalized hydrophobic resins such that they are easily redispersed in water or solvent to form stable nanoparticle dispersions suitable for use in ink jet inks. A prototype …

Mechanical and electrical characterization of carbon Black-doped closed-cell Polydimethylsiloxane (PDMS) foam
Carbon Black-doped Polydimethylsiloxane (CB-PDMS) can be used as a pressure sensing material due to its piezoresistive properties. The sensitivity of such a sensor is in part dependent on the stiffness of the material. A closed-cell CB-PDMS foam is being explored as a possible flexible, …
