Abstract
Ternary blend system of linear low density polyethylene (LLDPE), low density polyethylene (LDPE) and poly lactic acid (PLA) compatibilised with maleic anhydride grafted polyethylene (MA-g-PE) has been reinforced by chemically modified nano calcium carbonate (nano-CaCO3). The mechanical, optical, thermal and morphological properties of the reinforced ternary blend have been evaluated. Mechanical properties are superior at 1 phr of nano-CaCO3 filler, except elongation at break and burst strength. Optical properties study indicates that haze and transmittance have been affected due to the nucleating effect of nano-CaCO3 on the matrix. SEM micrographs show reasonably well bonding between the matrix and the reinforcement material. 9 Refs.
