Carbon nanomaterials have increasingly gained interest due to their capability of forming various allotropes, including nanotubes, fullerenes, diamond, amorphous carbon, and more recently, graphene. Carbon nanomaterials or nanostructures offer exceptional flexibility in tailoring various properties for specific purposes due to their chemical inertness. For example, they have resistance to acidic or basic media, structural stability at high temperatures in the absence of air, and tunable chemical nature of hydrophobicity. Different physical forms of carbon materials in nanoscale, including thin films, graphene foams or sponges, carbon nanotube forests, carbon fibers, carbon nanowalls, and porous carbon materials, can lead to a variety of functions. In addition to chemical and physical modifications, the functions of carbon nanomaterials can be altered by adding or doping metal elements, such as gold, platinum, or silver. Carbon nanomaterials have been widely applied for use in energy, environment, water, biomedicine, and other fields.

The major goals of this special issue are to find novel fabrication methods for functional carbon nanomaterials and the modification or nanostructuring of carbon surfaces for novel functionalization in up-to-date applications. The issue will include research papers and article reviews covering a wide range of current progress on functional carbon nanomaterials. Potential topics include, but are not limited to:

• Fundamentals in the preparation of carbon nanomaterials, such as graphene, diamond, carbon nanotubes, amorphous carbon film, and fullerenes
• First-principles/ab-initio and molecular dynamics modeling and theoretical calculations on functionalization of carbon materials
• Synthesis and fabrication of novel nanostructured carbon materials
• Modification with chemical or physical methods and characterization for functional carbon nanomaterials or nanostructures
• Applications in hard coatings, energy storage and conversion, water filtration, catalysts, and biomedical coatings
