Polymer Nanocomposites as Candidates for Tribological Applications

Abstract:

Article Preview

To develop wear resistant nanocomposite coating materials, the authors treated nanosilica first by introducing a certain amount of grafting polymers onto the particles in terms of an irradiation technique. Through irradiation grafting, the nanoparticle agglomerates turn into a nano-composite microstructure, which in turn built up a strong interfacial interaction with the surrounding epoxy matrix during the subsequent mixing and consolidation. The experimental results indicated that the addition of the grafted nanosilica into epoxy significantly reduced wear rate and frictional coefficient of the matrix at low filler loading. Compared with the cases of microsized silica and untreated nanosilica, the employment of grafted nanosilica provided the composites with much higher tribological performance enhancement efficiency.
