General description

This grade of vapor-grown carbon nanofiber (VGCF) is recommended for imparting thermal and electrical conductivity to polymer matrices. It is also recommended for applications, which require the absence of metals. Carbon nanofibers (CNFs) are discontinuous and highly graphitic in nature. CNFs are highly compatible with most polymer processing techniques, and can be dispersed in an isotropic or anisotropic mode. They have excellent mechanical properties, high electrical conductivity, and high thermal conductivity, which can be imparted to a wide range of matrices including thermoplastics, thermosets, elastomers, ceramics, and metals. Carbon nanofibers also have a unique surface state, which facilitates functionalization and other surface modification techniques to tailor/engineer the nanofiber to the host polymer or application.
