摘要: Bio-based nanocomposites were prepared from starch and soft wood with water as the solvent via a green route great engineering aspects. Methyl methacrylate (MMA) modified starch, dimethyloldihydroxyethyleneurea (DMDHEU), flour, glycerol, montmorillonite clay (MMT) employed to prepare (WSNC). Three different percentages of MMT composites properties studied through limiting oxygen index test (LOI), mechanical thermogravimetric analysis (TGA). The delamination silicate layers morphology incorporated explained by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission (TEM). WSNC 3 phr (parts per hundred) showed better compared containing 1 5 phr MMT. enhanced flexural strength tensile 28% 112%, respectively, free composites. having also exhibited an outstanding improvement in thermal stability, resistance, flame retardancy properties.
