dc.description.abstractHydrogel is a hydrophilic material and can be used as wound dressing, since it can be biocompatible, potencial drug delivery system and absorbent of fluids. Hydrogels can be produced by one or more hydrophilic polymers; natural or synthetic. These materials have a three-dimensional network of cross-linked polymer chains, and may be synthetized by gamma radiation that crosslinks and sterilizes the hydrogel, in one step. PVP-clays composites show, through many ways of swellings tests, an increase of fluid absorption properties. These properties can be modified when using a mechanical or sonication dispersion process of clay in water, before polymer mixture preparation. The aim of the present study is to prepare a hydrogel with PVP-clay containing poly (N-vinyl-2-pyrrolidone), poly (ethylene glycol), Agar and Laponite clay processed by gamma radiation. The influence of clay dispersion process, clay/polymer ratio in the hydrogel and type of sample (dried or not) were investigate according to the methodology of gel fraction, swelling tests, Scanning electronic microscopy (SEM). According to the results of water swelling, the clay sonication process is more effective than mechanical dispersion, however, if the sample was dried in stove before the swelling test, the results were similar, probable owing to morphology modification promoted by the stove drying process.pt_BR
