Effect of Electron Beam Irradiation on Mechanical and Thermal Properties of Ethylene Vinyl Acetate/Polyamide 6/High Density Polyethylene Nanocomposite

Abstract:

The effect of electron beam irradiation on mechanical properties of Ethylene vinyl acetate (EVA) with polyamide 6/high density polyethylene/HDPE-g-MAH and montmorillonite (MMT) were prepared by melt blending the characterization were investigated. The composites were characterized by Fourier Transform Infrared (FTIR) spectrophotometer and Thermogravimetric Analyzer (TGA) The samples were cross-linked by electron beam and irradiated at the dosage range of 0-200 kGy and 3.0 MeV. The mechanical properties of the samples which are tensile test and flexural test were measured by universal tensile machine whiles hardness was measured using Rockwell hardness tester. The gel content was performed to determine the formation of crosslinking and it showed improvement with increase dose up to 150 kGy. The result shows the increasing of tensile strength, tensile modulus, and hardness at the dosage 150 kGy but slightly decline at dose up to 200 kGy. Meanwhile TGA test showed that both irradiated and unirradiated samples have same trend characterization but irradiated samples are slightly more thermal stability. As a conclusion the electron beam irradiation enhance mechanical and thermal properties of ethylene vinyl acetate/polyamide 6/high density polyethylene nanocomposite.
