Abstract
A method for producing carbon nanotubes uses a polymer as a raw material to undergo in situ thermal decomposition. The method includes steps of mixing the polymer and metallic catalyst through a multiple heating stage process of in-situ thermal decomposition to carbonize the polymer and release carbon elements to produce carbon nanotubes. Advantages of the present invention include easy to prepare, low temperature in manipulation, low production cost, and high safety.
