| Abstract: | Water-based nanocomposite was synthesized using in-situ polymerization of Methyl Methacrylate. Nano-CaCO3 was added during polymerization along with aqueous solution of surfactant. Quantity of nano-CaCO3 was varied as 0, 2 and 4% of monomer quantity. XRD gram shows the presence of nano-CaCO3, which causes the crystalline nature to nanocomposites. TEM images of nano-CaCO3 show cubic structure. Synthesis of nanocomposite follows pseudo–first-order kinetics polymerization. PMMA-4% CaCO3 nanocomposite showed significant improvement in UV absorbance and in mechanical properties like adhesion, scratch resistance as compared to neat PMMA and 2% CaCO3 nanocomposite. |
