Fabrication and characterization chitosan-graft-poly (methyl vinyl ketone) nanoporous microspheres |
| 초록 |
Chitosan(CS) is a well-known natural polysaccharide with good biocompatibility and biodegradability. Graft copolymerization of poly (methyl vinyl ketone)[PMVK] onto chitosan was conducted by free radical method using KPS or CAN as an initiator. Nanoporous microspheres were synthesized by water-in-oil(W/O) emulsion method with glutaraldehyde(GA), Tween80® as crosslinking agent and emulsifier, followed by UV irradiation to confer nanopores by photodegradation of PMVK. Graft copolymer was characterized by FT-IR and NMR spectroscopies. SEM showed CS-g-PMVK microspheres were approximately 5 ㎛ in diameter with rough surface due to photodegradation. CS-g-PMVK could have potential applications for drug delivery system |
