Preparation of Spherical, Monodisperse Carbon Particles in the 1 to 10 Micron Particle Size Range for Use in Various Fields of Application

摘要

A family of spherical, monodisperse carbon particles has been synthesized in the 1 to 10 micron particlesize range. These carbons have been prepared using polymeric spheres which have been pyrolyzed and/orgraphitized to produce carbon spheres of similar size distributions. Syntheses of the polymers using amodified microemulsion process to produce monodisperse particle size distributions, allow for theprocessing of the carbon spheres with subsequent monodisperse properties.The use of both porous and non-porous polymer precursors allows for the processing of both porous andnon-porous carbons. The tailoring of the polymer thus leads to carbons with different physical and surfacechemistry properties. The range of furnace temperatures from 300°C to 3000°C augments the performancecharacteristics of the carbons formed. The variety of carbons prepared allows for adsorption applications inseveral fields of interest.
