Preparation and characterization of hydrogel microspheres of poly(vinyl alcohol) and poly(acrylic acid) interpenetrating polymer networks |
| 초록 |
The novel hydrogel microspheres, which consisted of poly(vinyl alcohol) and poly(acrylic acid) interpenetrating polymer networks, were prepared by emulsion radical polymerization. These hydrogel microspheres had the three-dimensional networks that were capable of imbibing large quantities of water and releasing drugs at the controlled rates. The hydrogel microsperes exhibited a sensitive pH-responsiveness much better at the basic pH range than at the acidic pH range. FT-IR spectra were also used to confirm the composition of the hydrogel microspheres. The particle size and morphology of hydrogel microspheres were studied by using scanning electron microscope. |
