Mechanical and Sorption Properties of the Organically Modified Clay Reinforced Biodegradable Starch Nanocomposites

In this research manufacturing technology of organically modified montmorillonite (OMMT) clay reinforced biodegradable starch nanocomposites is described. In order to raise applicability of the nanocomposites, base starch matrix is plasticized be means of glycerol and water in a strictly defined component ratio. For optimization of interfacial interaction in the clay galleries certain amount of modifying agent is introduced in the system during manufacturing of the nanocomposites by solution casting method. OMMT content is varied between 1 and 12 wt. %. Structural, calorimetric, mechanical and sorptive properties of these nanocomposites are investigated
