Well-defined Carbon Nanoparticles Prepared from Water Soluble Shell Cross-linked Micelles Containing Polyacrylonitrile Cores

Well-defined carbon nanoparticles were developed through pyrolysis of shell cross-linked poly(acrylic acid)-b-polyacrylonitrile nanoparticles prepared by micellization and cross-linking of amphiphilic block copolymer in aqueous systems. These low-dimensional nanoobjects were characterized by AFM and DLS. FTIR and Raman spectroscopy confirmed their partially graphitic characters. Nanostructured carbons prepared according to this route are expected to find many applications, such as antistatic coatings, materials for field emitters, specialized electrodes, sensors, etc. One of the particularly important advantages of this route is the use of covalently stabilized water-soluble precursors, thus facilitating environmentally friendly processing conditions. In addition, manipulation of solvent systems and copolymer composition may open the way to extend the presented approach to other low dimensional nanostructures similar to those observed in other block copolymer systems.
