Influence of CaCO_3 Nanoparticles Shape on Thermal and Crystallization Behavior of Isotactic Polypropylene Based Nanocomposites

摘要

The effect of calcium carbonate nanopartides with different shapes (spherical and elongated) on the thermal properties and crystallisation behaviour of isotactic PP was investigated.Calcium carbonate nanopartides were covered with an appropriate coating agent to improve the interfacial adhesion between the filler and the polyolefin matrix.The nanocomposites were prepared by melt mixing and subsequent compression moulding.
