The effect of CaCO3 nanoparticles on mechanical and morphological properties of PLA/CS/CaCO3 composites

Blending of chitosan (CS) with suitable polymer matrix is an often used and effective method to improve the physical and mechanical properties of blend composites. In this study, chitosan (CS) natural polymer filled Poly(lactic acid) (PLA) and calcium carbonate (CaCO3) nanoparticles composites were...
