Effects of thermal aging on structure and dielectric properties of polypropylene/calcium carbonate nanocomposites

This paper reports on an investigation of the effect of thermal aging on the structure and dielectric properties of unfilled polypropylene (PP) and PP nanocomposites containing 1 wt%, 2 wt%, and 5 wt% of calcium carbonate (CaCO3) nanofiller. Three different aging temperatures were considered, i.e.,...
