Modified potato starch was used as matrix with water and sorbitol as plasticizers and with 5wt.% of either of the reinforcements. Two methods were explored to prepare samples for transmission electron microscopy (TEM) examination; chemical fixation and freeze etching. It was possible to characterize the nanostructure both parallel and perpendicular to the nanocomposite surface by the freeze etching technique. Both nanocomposites showed well-distributed reinforcements in the starch matrix. Dynamic mechanical thermal analysis showed that the storage modulus was significantly improved at elevated temperatures, especially for the layered silicate nanocomposite. Both nanocomposites showed a significant improvement in tensile properties compared to the pure matrix.
