Green Nanocomposites from Renewable Resources: Effect of Plasticizer on the Structure and Material Properties of Clay-filled Starch

摘要: Nanocomposites of starch were prepared via different addition sequences plasticizer and clay by the solution method. The extent dispersion filler was evaluated wide angle X-ray diffractometry (WAXD) in resulting composites. Thermal stability, mechanical properties water absorption studies conducted to measure material whereas FT-IR spectroscopy used study microdomain structure sequence components (starch /plasticizer (glycerol) / clay) had a significant effect on nature composites formed accordingly altered. Glycerol both have tendency penetrate into silicate layers but penetration glycerol is favored owing its smaller molecule size. becomes highly heterogeneous product more brittle when plasticized before filling with due formation bulky from electrostatic attractions between plasticizer. It concluded that best can be obtained if added after mixing matrix.
