Nanocomposite Prepared from in-Situ Grafting of Polypyrrole to Aminobenzoyl-Functionalized Multi-Walled Carbon Nanotube and Its Electrochemical Properties |
| 초록 |
We report functionalization of multi-walled carbon nanotube (MWCNT) with 4-aminobenzoic acid by a ‘direct’ Friedel-Crafts acylation reaction in a mild polyphosphoric acid (PPA)/phosphorous pentoxide (P2O5) medium. The resulting 4-aminobenzoyl-functionalized multi-walled carbon nanotube (AF-MWCNT) was used as a platform for the grafting of polypyrrole (PPy) in ammonium persulfate/aqueous hydrochloric acid solution to produce PPy grafted MWCNT (PPy-g-MWCNT) composite. After dedoping with alkaline treatment, PPy-g-MWCNT displayed 20 times higher electrical conductivity than that of PPy. In addition, the capacitance of PPy-g-MWCNT composite was remarkably improved compared with that of PPy homopolymer, suggesting that an efficient electron transfer between PPy and MWCNT was possible through covalent links. |
