Synthesis and Characterization of Thermosensitive Block Copolymers Composed of Poly(N-isopropylacrylamide) and Poly(ε-caprolactone) |
| 초록 |
The synthesis and characteristics of amphiphilic block copolymers have been much interest because of he unique molecular architecture and different chemical nature. In this study, the well-defined poly (ε -caprolactone) (PCL)/poly (N-isopropylacrylamide) (PNIPAAm) diblock copolymers were synthesized through combining radical polymerization of NIPPAAm and the controlled coordination-insertion ring-opening polymerization of CL using an aluminum alkoxide macroinitiator formed from the equimolar reaction of triethylaluminum with hydroxy-terminated PNIPAAm (PNIPAAm-OH). Molecular characterization of PCL/PNIPAAm diblock copolymers was confirmed through 1H-NMR, FT-IR and GPC analysis. Polymeric micelles composed of PCL as a hydrophobic core and PNIPAAm as a hydrophilic shell were prepared by a diafiltration method. The sizes and shapes of the thermosensitive micelles were investigated with a dynamic light scattering spectrometer and with a TEM. |
