Polymer graftingonto the surface of CNTs/TiO2 nanoparticlesby photocatalytic polymerization |
| 초록 |
In this work, a simple and efficient method was presented for the preparation of polymer-grafted CNT/TiO2 by a photocatalytic polymerization. PMMA chains were directly grafted to the surface of the CNT/TiO2 nanoparticles in water under sunlight illumination. FT-IR and TEM results demonstrated that there existed strong chemical bonding at the interface between CNT/TiO2 nanoparticles and PMMA chains. The thermal stability of the grafted polymer was dramatically elevated compared to that of pure PMMA according to the TGA results. Moreover, the resulted polymer exhibited much higher melting temperature from traditional stereoregular PMMA by controlling the conformation of polymer chains growing in the highly restricted space on the surface of nanoparticles. |
