Adsorption properties and physical characterization of carrageenan/alginate macro and microspheres blended with flexible chain polymers

This work addresses the production and characterization of alginate-carrageenan matrixes, cross-linked with epichlorohydrin in the presence of different flexible chain polymers: polyvinyl alcohol and polyvinyl pyrrolidine. These matrixes were obtained by ionotropic gelation in two different sizes: macro and microspheres. The different systems were characterized by optical microscopy, SEM and TGA. The obtained matrixes showed differences in their water content, shape and roughness due to the addition of flexible chain polymers into their composition.
