제목 Preparation and Characterization of pH-sensitive Poly(acrylic acid)/Poly(vinyl alcohol) Microcapsules containing Theophyline
초록 The preparation of pH-sensitive poly(acrylic acid) (PAAc) / poly(vinyl alcohol) (PVA) microcapsules and the features of these microcapsules were studied in terms of the drug delivery behavior. The pH-sensitive poly(acrylic acid) (PAAc) / poly(vinyl alcohol) (PVA) microcapsules were prepared by using theophyline-containing oil in the water-in-oil emulsion polymerization. The effects of emulsifier and stirring rate on the size and the shape of microcapsules were investigated by using image analyzer and scanning electron microscope. The controlled drug release behavior was studied by UV/VIS spectroscopy. FT-IR spectra were also used to confirm the composition of the microcapsules.
