AB  - A nanocomposite system comprised by a biodegradable polymer, poly(butylene succinate-co-lactate) (PBSL), and a Brazilian nanoclay (VMF1) containing montmorillonite (MMT) and kaolinite (K) is used to prepare microcapsules by solvent diffusion method. The nanocomposite PBSL/MMT-K and the microcapsules were characterized by wide angle X-ray diffractometry (XRD), scanning electron microscopy (SEM), stereomicroscopy, and Fourier transform infrared spectroscopy (FTIR). The overall results show that PBSL/MMT-K presents intercalated nanostructure of montmorillonite and kaolinite, both PBSL and PBSL/MMT-K proved to be very effective as matrix for production of uniform spherical microcapsules, as surveyed by scanning electron microscopy and stereomicroscopy. The spherical microcapsules repared from PBSL/MMT-K nanocomposite presented diameters smaller than 50Ž¼m, and can probably be used as delivery systems.
