Preparation and Properties of Low Density Polyethylene Film Modified by Zeolite and Nanoclay

Abstract

PE-LD samples containing two types of filler in concentrations of 2-10 wt.% (zeolite TMAZ 7 and nanoclay Cloisite 20A). The microstructural and morphological changes as well as mechanical features of samples were characterized by scanning electronic microscopy (SEM) and by tensile tests. The thermal degradation of PE-LD composites were achieved using thermogravimetric analysis (TGA). The permeability, the diffusion and the solubility constants of the gases in modified PE-LD films were calculated and the gas separation (N 2 / O 2 ; O 2 /CO 2 ) ability was determined. In the presence of nanoparticles, at lower content, the value of oxygen permeability of PE-LD decreases.

Fabrication of LLDPE based biodegradable composite incorporated with leather shavings and buffing dust: An approach for waste management

“…In addition, the mechanical properties were also found higher than the leather fiber/natural rubber and buffing/NBR based composites 12,39,40 . It may happen because of the different matrix and fibers, variation of their ratio and fabrication methodology 8,32,36,45 . However, the leather composites prepared with PLA and PVA showed higher tensile strength than the tensile strength of LLDPE based composite films.…”

“…4,5,31 Suitable filler matrix ratio and other processing variables in extrusion process like screw profiles, screw speed and feeding rate are critical to prevent the agglomeration of fibers and getting a uniform fiber/matrix interaction. 35,36,[44][45][46] The surface morphology of those fabricated composite films validates uniformity of the surface and better interactions between LB-LLDPE and LS-LLDPE.…”

Because PVA and PLA have intra-molecular cross-linked structures, confirmed network development between their chains resulting in enhanced mechanical characteristics.…”

Effect of nanoclay on mechanical and thermal properties of triblock SBS (styrene–butadiene–styrene) and its binary blend nanocomposites: comparison between polyethylene and polystyrene

“…Strong interaction leads to improving the mechanical properties while weak interaction deteriorates the mechanical properties. It is generally known that improved interfacial adhesion between the polymer matrix and the clay is a requirement for clay exfoliation into the matrix and subsequently for improved mechanical properties [39]. Sample SBS70/PE30 containing 1 wt-% nanoclay showed the highest tensile strength compared to other samples.…”

Influence of polybenzimidazole nanoparticle on the thermo-mechanical characteristics of high density polyethylene composite

“…Nearly two fold jump in the properties were observed by the authors. Similalry, Ščetar et al [20] investigated the characteristics of low density polyethylene films that had been treated with Zeolite and nanoclay. SEM and tensile tests were used to describe the microstructural and morphological changes, as well as the mechanical properties of the samples, in this study.…”
