Distinct affinities between the organic and inorganic phases were observed in nanocomposites prepared through a colloidal route with carboxylated nitrile rubber and modified silica nanoparticles, which resulted in variable mechanical properties and improved thermal stability. Nanoparticles with modified surface affected the macromolecular arrangements of the elastomeric matrix, changing the fin...

The paper presents the results of a study dilatometric properties thermoplastic elastomer nanocomposites based on mixtures random polypropylene, nitrile butadiene rubber, compatibilizer - copolymer polypropylene with maleic anhydride. Nanosized bentonite particles were used as filler. concentration nanoparticles was varied in range 1.0-20 wt %. values free and occupied specific volumes determin...
Abstract This work shows an innovative application for electric arc furnace (EAF) slag: its use as a filler nitrile butadiene rubber (NBR). Composites with various EAF slag contents were tested. It was found that the polymer matrix significantly reduces leaching of (determined according to standard CEN-EN 12457-2) incorporated in NBR. The processability characteristics determined by rheometric ...
The gel to carbonate precipitate route has been used for the synthesis of Ni1-xZnxFe2O4 (x = 0, 0.25, 0.5 and 0.75) bulk inverse spinel ferrite powder samples. The optimal zinc (50%) substitution has shown the maximum saturation magnetic moment and resulted into the maximum magnetic loss tangent (tanδm) > -1.2 over the entire 2-10 GHz frequency range with an optimum value ~-1.75 at 6 GHz. Ni0.5...
