Polymeric particulate composites with thermoplastics are of great practical importance due to their simple possibility of modifying mechanical properties and reducing the price/volume ratio of the resulting material. Fillers often do not directly face the matrix molecules in their bulk macro conformations. Both filler and interface properties as well as filler particles dispersion have a great effect on the mechanical properties. The system PP homopolymer + CaCO3 is used in the presented study. The commercial available CaCO3 nanoparticles are of tens nm dimension but they typically form agglomerates with the size up to 10 microns. The plasma treatment by ambient air operating surface discharge is used for the filler particles activation. Composites with well dispersed particles with agglomerates smaller than 100 nm are prepared using this activated filler material. The influence of morphology on mechanical properties is studied and compared with the commercially available system.
