26-07-2021· Calcium carbonate is typically obtained by grinding natural minerals or by the carbonation of calcium hydroxide. Calcite, the most stable polymorph of calcium carbonate, has drawn much attention due to its broad application potential [7-9]. It is mainly used as fillers to control the mechanical properties of polymer matrices.
PLA nanocomposites with stearate coated precipitated calcium carbonate (PCC) and halloysite natural nanotubes (HNT) were prepared by melt extrusion. The crystallization behavior, mechanical properties, thermal dynamical mechanical analysis (DMTA), and the morphology of the PCC/PLA, HNT/PLA, and HNT/PCC/PLA composites were discussed. Compared to halloysite nanotubes, PCC nanoparticles …
