Low density polyethylene/closite 20A nanocomposites with different organoclay contents were made in the current study by a melt mixing technique with two different compatibilizers of varying contents: low molecular weight oxidized polyethylene and low molecular weight trimethoxysilyl modified polybutadiene. The inclusion of compatibilizers and concentrations of organoclay were analyzed in relation to the mechanical and thermal properties of the nanocomposites. The dispersibility of the silicate clay in the nanocomposites was investigated using transmission electron microscopy. It was discovered that organosilane created a more exfoliated structure and increased clay dispersion in comparison to the low molecular weight oxidized polyethylene. “A dynamic oscillatory rheometer” was used to analyze the samples’ rheological behavior in the linear viscoelastic zone. Tensile strength, yield strength, and tensile modulus were all higher in the organosilane compatibilized system than in the uncompatibilized system, and much higher in the low molecular weight oxidized polyethylene compatibilized case. The crystallization characteristics of compatibilized and uncompatibilized nanocomposites were investigated using differential scanning calorimetry. The inclusion of compatibilizers raised the crystallization temperature due to the heterogeneous nucleation impact of organoclay on low density polyethylene, according to the results of differential scanning calorimetry.

Keywords: Films, organoclay, crystallization behavior, mechanical properties, polyethylene
