Abstract
This report demonstrates the successful use of hybrid nanoparticles of SiO2 and TiO2 in cross-linked polyethylene (XLPE) and reports the comparison of mechanical properties and thermal stability of XLPE/SiO2/TiO2 nanocomposites compared to XLPE/SiO2, at different filler concentrations and with neat XLPE. In the present system of XLPE/SiO2 nanocomposites, tensile strength and thermal stability show an increasing trend with nanoparticles, followed by a decaying trend at higher filler loading, whereas in XLPE/SiO2/TiO2 composites the property improvement is directly proportional to the filler concentration by avoiding the possibility for aggregation. It is found that the hybrid nanoparticles are efficiently dispersed in XLPE matrix, have the potential to reduce the tendency of aggregation by the combined effect of surface treatment on the nanoparticles and difference in surface characteristics of two kinds of nanoparticles. This results a direct correlation in property improvement with nanofiller concentration. This structure–property correlation is established using TEM images.
