Carbon Nanotubes Prepared by Spinning and Carbonizing Fine Core-Shell Polymer Microspheres

Abstract

Carbon nanotubes prepared from core–shell polymer particles are reported. As depicted in the Figure, polymethylmethacrylate (PMMA) core/polyacrylonitrile (PAN) shell microspheres are blended with a PMMA matrix, spun, and elongated. Then the shell is stabilized and finally carbonized to produce contaminant-free carbon nanotubes.
