Abstract

This research work is carried out in order to enhance thermal, mechanical and physical properties of linear low density polyethylene-silica (LLDPE-SiO2) polymer nanocomposites by varying filler size vastly from 20 nm to 145 nm and keeping filler weight fraction constant. Here silica nanoparticles are used as filler with linear low density polyethylene (LLDPE) matrix to prepare four series of thermoplastic nanocomposites. Size controlled silica nanoparticles are synthesized by optimizing reaction temperature to ensure their uniform dispersion in polymer matrix. Thermal stability, hardness and tensile strength of polymer nanocomposites have been investigated as functions of silica nanoparticles size in polymer matrix. Experimental results show better thermal stability, higher hardness, higher tensile strength and lower density of LLDPE-SiO2 nanocomposites with decrease in silica nanoparticle size.
