1. A method of fabricating a polyacrylonitrile (PACN) and deriving a nanostructured superstructure shape, comprising:
a) synthesizing in a one-pot free radical polymerization synthesis a PACN structure using acrylonitrile (ACN) as a monomer, azobisisobutyronitrile (AIBN) as an initiator and an organic solvent; and
b) converting the PACN structure into a nanostructured superstructure shape by stabilizing and carbonizing the PACN structure, wherein the stabilizing step comprises an oxidative reaction step in air at a temperature in a range of 180° C. to 300° C. with a ramping rate of 0.1° C./min to 5° C./min in a range of 2 to 12 hours and the carbonizing step comprises pyrolyzing the stabilized PACN structure at a temperature ranging from 600° C. to 1500° C. in an inert gas atmosphere or vacuum condition.
