Structural study of polyethylene/montmorillonite systems

Abstract

The effect of modification of montmorillonite (with 3- aminopropyltrimethoxysilane or hexadecyltrimethylammonium chloride) on the mechanical properties of the composites based on HDPE Hostalen ACP 5831 with the modified montmorillonite as filler, was studied. The structures of the fillers and nanocomposites were characterised by the scanning electron microscopy and X-ray diffraction study. The effect of the filler modification on the mechanical parameters of the nanocomposites and their structure was assessed on the basis of determination of the mechanical resistance, elongation at maximum tearing stress, bending strength, deformation at the maximum force and elasticity modulus on bending (three-point bending strength).
