4-Aminobenzoic Acid Functionalized PAN-Base Carbon Fibers in Mild Polyphosphoric Acid/Phosphorous Pentoxide


Article Preview

Pristine polyacrylonitrile (PAN)-base carbon fibers (P-CFs) was functionalized with 4-Aminobenzoic acid via ‘‘direct’’ Friedel-Crafts acylation in a mild reaction medium of polyphosphoric acid (PPA)/phosphorous pentoxid (P2O5). Fourier transform infrared spectroscopy, Raman spectroscopy, Scanning electron microscopy were applied in this study to demonstrate that PAN-base carbon fibers inherently have functional groups on their surface as a result of the reaction. The overall evidence indicates that the 4-Aminobenzoic acid functionalization of carbon fibers can be achieved without oxidation as pre-treatment. Thus, amine functionalized CFs(F-CFs)can be synthesized, without disrupting the strength of the carbon fibers.
