Carbon Nanoparticles made from PAN‐based Precursors

Abstract

We introduce the novel carbon nanoparticles with specific structure and feature. They are made from precursors of polyacrylonitrile(PAN)-based polymer in the original process. The shape and structure of the derived carbon products, which are designed by selecting the size and molding the precursors of polymer, are very uniform. Also, these particles showing their forms individually, have the excellent dispersibility in some mediums and show the functional property. Since they can be prepared corresponding to the applications, they are expected to be developed to many applications by practically using their functions and properties.

Water-dispersible “carbon nanopods” with controllable graphene layer orientation

“…Finally, the carbon was liberated from the silica matrix by washing with aqueous NaOH solution. Previously, we tried to prepare CNPs without the silica matrix, 5 but most of the polymer nanoparticles collapsed during the carbonization process.…”
