Interfacial and mechanical properties of polypropylene/silica nano- and microcomposites
Various silica grades differing in particle size (micro- vs. nanosilica) and surface modification (untreated vs. modified surface) have affected interfacial and mechanical properties of compression molded polypropylene composites with 2, 4, 6, 8 vol% of added silica. Mechanical properties have been influenced primary by combination of stiff fillers and tough polypropylene matrix and additionaly by restructured matrix. Namely, silica particles with different surface properties have influenced nucleation and spherulite growth differently affecting thus tensile properties of the composites. All composites exhibited best tensile strength in silica content range 2 - 6 vol%.
