Abstract
The goal of this work is to modify surface of calcium carbonate nanoparticles with silica (CaCO3@SiO2) via sol-gel process, and to investigate the influence of CaCO3@SiO2 on mechanical properties and fracture behavior of poly(lactic acid) nanocomposite. Modified CaCO3@SiO2 nanoparticles were prepared with different Si/Ca ratios. It is found that the Si:Ca wt% ratio was increased with respect to the Si:Ca mole ratio used in the reaction. Incorporating CaCO3@SiO2 of 5 wt% increased elastic modulus, %elongation at break and notched impact strength of PLA nanocomposites, which these properties of CaCO3@SiO2-PLA nanocomposite was increased with respect to increasing of SiO2 content on the surface of CaCO3 nano-particles. This implies that better compatibility between polymer matrix and filler was achieved after modification surface of CaCO3 with SiO2 layers.
