Original Abstract
Polymeric particulate composites with thermoplastics, especially polypropylene (PP) matrix and mineral fillers, are of great practical importance due to their simple possibility of modifying mechanical properties and reducing the price/volume ratio of resulting material. The commercial available CaCO3 nano particles are of tens nm dimensions but they typically form much bigger agglomerates with the size up to 10 microns. The surface DBD discharge in ambient air at atmospheric pressure was used for the nanoparticles surface modification. The agglomerates size was decreased of about one order during a few seconds of the plasma treatment. The treated particles were applied into a polypropylene matrix, and nanocomposite properties were studied by various techniques.
