Carbon nanofibers (CNFs) are an extremely versatile material. CNFs are highly graphitic, discontinuous, and highly compatible with a variety of polymer processing techniques, and they are amenable to both isotropic or anisotropic dispersal. In addition, CNFs possess excellent mechanical properties, including high electrical and thermal conductivity, which are compatible with a wide range of materials such as metals, ceramics, thermoplastics, and elastomers. The surface state of carbon nanofibers is unique, allowing them to be easily modified and specifically tailored to any number of applications. Carbon nanofibers from ACS Materials are available in a powder form and are produced using CVD.
