Preparation of Porous Carbon with Defluorination of PTFE by Radical Anion

Application of Carbon Materials Derived from Fluorocarbons in an Electrochemical Capacitor

“…After the PTFE undergoes defluorination, the growth of the template fluoride particle is stimulated in the carbon matrix through annealing at high temperature before the fluoride is removed, which thereby results in control of the pore size distribution. Figure 17.6 shows X-ray diffraction (XRD) patterns of the carbon matrix products from the defluorinated PTFE using lithium-naphthalene anion complexes and then heat-treated at different temperatures, and Figure 17.7 shows a comparison of the nitrogen physisorption isotherms and the pore size distributions of the porous carbons after removal of the lithium fluoride [11]. It is clear that the XRD peaks of LiF grow sharper when the heat treatment is applied at higher temperatures, which facilitates the growth of the LiF particles in the carbon matrix.…”
