Abstract
A high yield method for chemically synthesizing low polydispersivity carbon microspheres, nanospheres, nanocrystals, nanotubes, or nanofibers comprising dispersing a self-polymerizing end-capped polyyne in a solvent; heating the dispersed self-polymerizing end-capped tetrayne to form a polymeric material selected from the group consisting of polymer microspheres, polymer nanospheres, polymer nanocrystals, polymer nanotubes, and polymer nanofibers; and pyrolyzing the polymeric material to form a carbon material selected from the group consisting of carbon microspheres, carbon nanospheres, carbon nanocrystals carbon nanotubes, and carbon nanofibers, wherein the polydispersivity is less than 2.
Claims40
