SYNTHESIS AND CHARACTERIZATION OF POLYPROPYLENE-SILICA, ALUMINA AND TITANIA NANOPARTICLES, PREPARED BY MELTING

Polypropylene composites with 5 to 10% of SiO2, Al2O3 y TiO2 nanoparticles were synthesized. The oxides were obtained using the sol-gel technique and were added to the molten polypropylene. The morphology of nanoparticles was observed by scanning electron microscopy and showed that the incorporation...
