New Developments in the Formation of Nanocomposites between Starch and Clay

Manar Ghyath Abd-Almutalib Al-Mosawy and Zeyad Kadhim Oleiwi


Biodegradable polymers, like Polycaprolactone (PCL), have recently received a lot of attention in the science establishment because of the growing global interest in non - petroleum-based polymeric materials. 3-amino - 4 - ((3-hydroxyphenyl) diazenyl) - N(pyrimidine-2-yl) benzenesulfonamide (AZO) one of the organic materials used to reconfigure natural clay (sodium montmorillonite). The clay particles were modified by stirring them in an aqueous medium of AZO-MMT, which increased the wavelength from 1.27 to 2.04 nm. The reconfigured clay would have been used to make PCL/corn-starch mixture nanocomposites. They were created by combining 0.5–5% AZO-MMT. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) were utilized to characterize the interaction of the modifier in the clay layer. The nanocomposites were prepared by solution casting method the reconfigured clay and a PCL/corn-starch mixture at a weight ratio of 80/20, which leads to an increase in the scope of tensile strength which that considers the biggest blend. The results of survey electron microscopy, transmission electron microscopy, and XRD was proved the creation of nanocomposites materials. Additionally, that PBS/corn-starch reconfigured clay nanocomposites exhibit that superior thermal stability significantly and a great increase over the PCL/corn-starch mixture.
