| 제목 | Synthesis of Poly(L-lactide)-graft-carbon Nanotube via Ring Opening Polymerization |
| 초록 | A number of methods have been attempted for the preparation of polymer/carbon nanotube composites: solution or melt mixing of the carbon nanotubes (CNT) with preformed polymers, electrospinning, in-situ polymerization, surfactant-assisted processing of CNTcomposites, and chemical modification of the incorporated CNT. In the present study, we introduced a new technology to obtain CNT/poly(L-lactide) composites. The interfacial bonding was enhanced through covalent reaction between the polymer chain and the functionalized CNTs to enlarge the applicability of the resulting composites. DMF was selected as the solvent for the ring-opening polymerization because it dissolved both the monomer and the PLLA unbound to the CNT. Moreover it allows a high reaction temperature to make the catalyst highly active. The resulting CNT-g-poly(L-lactide) hybrid was characterized by TEM, SEM and TGA. |
