Preparation of Polyketone grafted Multi-Walled Carbon Nanotubes with grignard reagent and Polyketone composite. |
| 초록 |
A pyrene derivative containing bromine and Magnesium groups were used to introduce functional groups into the multi-walled carbon nanotube(MWCNT). The PK reacted with functionalized MWCNT with the grignard reagent to produce PK grafted MWCNTs (PK-g-MWCNTs) which were used to produce PK-based composites by twin screw melting extruder. It has been shown that the alkyl groups of the Grignard reagents were reacted with ketone groups in PK. The interfacial adhesion energy between the PK and the functionalized MWCNT was calculated using the drop on fiber method combined with the general drop shape analysis. The interfacial adhesion energies measured in PK and PK-g-MWCNTs are the highest values obtained from PK and MWCNT, ensured the enhanced adhesion and the best homogeneous dispersion of MWCNT in the composites. The PK / PK-g-MWCNT composites showed higher mechanical properties than the PK / Pristine MWCNT composites at constant MWCNTs contents. |
