What Are Carbon Nanofibers?
Carbon nanofibers (CNFs) are quasi‑one‑dimensional carbon allotropes formed by the vertical stacking of graphene sheets. Their morphology yields a high aspect ratio and a surface area that facilitates strong interfacial bonding within polymer matrices, while their intrinsic strength and electrical conductivity enable multifunctional roles across composites, conductive inks, and energy storage components.
