ZnO nanoparticles (NPs) were anchored to SiO2 spherical nanoparticles by hydrolysis and condensation of Zn(CH3COO)2 in the presence of SiO2. The ZnO/SiO2 NPs were then blended with isoprene rubber. The immobilization of ZnO NPs on the silica surface, due to covalent SiAOAZn bonds provides a homogeneous dispersion of zinc in the rubber matrix and increases the accessibility of the curative reactants to Zn2+ ions. This improves the efficiency of the rubber curing and reduces the amount of used ZnO.

Abstract

ZnO nanoparticles (NPs) were anchored to SiO2 spherical nanoparticles by hydrolysis and condensation of Zn(CH3COO)2 in the presence of SiO2. The ZnO/SiO2 NPs were then blended with isoprene rubber. The immobilization of ZnO NPs on the silica surface, due to covalent SiAOAZn bonds provides a homogeneous dispersion of zinc in the rubber matrix and increases the accessibility of the curative reactants to Zn2+ ions. This improves the efficiency of the rubber curing and reduces the amount of used ZnO.
