A small carbon fiber diameter is one of the most important objectives in carbon fiber technology. This produces improved mechanical properties and a larger surface area per unit mass. Electro-spinning is able to produce polymer fibers with diameters ranging over several orders of magnitude, from the micrometer to the nanometer range. Optimization of electro-spinning process to produce the smallest nanofibers from high molecular weight emulsion polymerized PAN polymer with dimethylformamide has been investigated. Relationships between Berry_s number, spinning height, spinning angle and charge density and the diameter of the electro-spun PAN nanofiber have been established
