Zusammenfassung:The present invention refers to the obtention of nanocomposite materials of a chitosan biopolymeric matrix where oxide nanoparticles known as spinel ferrites are dispersed and stabilised, the materials resulting therefrom are films and powders with controllable magnetic characteristics, in virtue of the particle size and the type of spinel oxides immersed into the biopolymeric matrix. La presente invencion se refiere a la obtención de materiales nanocompuestos de matriz biopolimerica de quitosan donde nanoparticulas de oxido denominadas ferritas espinela se hallan dispersas y estabilizadas, siendo los materiales resultantes películas y polvos con caracteristicas magneticas controlables, en virtud del tamaño de particulas y el tipo de oxidos espinelas inmersas en la matriz biopolimerica.
