Functionalization of carbonaceous materials

Carbonaceous materials are key components of all innovative electrochemical devices and largely used as specific catalyst supports. We have the experience and know-how to functionalize such as materials with elemental fluorine and perfluorinated radicals in order to obtain composite materials that integrate the conductivity and high surface area properties of carbonaceous materials with properties of fluorinated one, such as high chemical and thermal stability, hydrophobicity and low surface energy. Functionalizations are made on:

  • Carbon Black
  • Hard Carbon
  • Diamond Like Carbon (DLC)
  • Single-Walled Carbon Nanotube’s (SWCNT’s)
  • Multi-Walled Carbon Nanotube’s (MWCNT’s)
  • Graphite

High relevance have the functionalization through perfluoropolyether (PEPE) radicals obtained by thermal decomposition of PFPE peroxide, that allows to link polymeric chains to carbonaceous materials. This kind of functionalizations confer a controlled enhancement in substrates hydrophobicity, until and over the threshold of superhydrophobicity. Moreover, the conductive properties of the materials are almost unchanged, allowing the use of this materials in electrochemical applications.
