GRAFTING OF POLYETHERKETONES ONTO GRAPHITE VIA IN-SITU POLYMERIZATION OF 3- AND 4- PHENOXYBENZOIC ACIDS IN POLYPHOSPHORIC ACID |
| 초록 |
We have established an optimum reaction conditionfor the in-situ polymerization of 3- and 4-phenoxybenzoic acids in the presence of graphite that was carried out in poly(phosphoric acid)/phosphorus pentoxide (PPA/P2O5; 1:4 w/w) medium. 3- and 4-phenoxybenzoic acids polymerize in PPA to form poly(oxy-1,3-phenylenecarbonyl-1,4-phenylene, mPEK) and poly(oxy-1,4-phenylenecarbonyl-1,4-phenylene, pPEK), respectively. The grafting of polyetherketones onto the surface of graphite was traced by elemental analysis (EA), thermogravimetric analysis(TGA), FT-IR spectroscopy as well as scanning electron microscopy (SEM). And the resulting materials implicate that graphite remained structurally intact under the mild acid, relatively high-shearing and hot polymerization conditions. It is also evident that under these reaction conditions, mPEK and pPEK were covalently attached onto the surface of graphite resulting in “hairy disk.” |
