Growth of bridging carbon nanofibers in cracks formed by heat-treating iron oxide thin sheets in acetylene gas
Source abstract
Abstract
We produced novel carbonnanofibers (CNFs) by oxidizing high-purity iron foil and then carburizing it in acetylene gas flow. This formed cracks in the heat-treated iron foil with CNFs bridging the two walls of each crack. The CNFs were drawn out from the walls as the crack opened during heat treatment. This will be a new method to grow and arrange carbon nanotubes and nanosheets without using metal nanoparticles or template substrates.
