Summary

Modified starch and sodium polyaspartate blend was used as a polymeric template for the preparation of a magnetic composites. Their structural and magnetic properties (by SEM, magnetometry, IR), as well as thermal stability and particle size distributions were characterized. The dependence between the magnetite content and magnetic susceptibility values is stressed. The study confirms the possibility to obtain magnetic composites from magnetite (Fe3O4) and the polymeric composite template based on carboxymethyl starch and sodium polyaspartate. The importance of these magnetic composites derives from the biodegradability of the template as well as the possibilities given by functional groups able to couple both magnetite and further bioactive substances.


Key words: carboxymethyl starch, sodium polyaspartate, magnetite, magnetic composite, structure, properties
