Effect of inorganic nanofillers on the impact behavior and fracture probability of industrial high-density polyethylene nanocomposite

Abstract

The main purpose of this work is to study how the morphology of nanofillers and dispersion and distribution level of inorganic nanofiller influence the impact behavior and fracture probability of inorganic filler filled industrial high-density polyethylene nanocomposites. For this study, nanoclay and nano-CaCO3 fillers–high-density polyethylene mixings (0, 1, 3, 5 wt.% high-density polyethylene) was prepared by melt-mixing method using a compounder system. The impact behavior was examined by charpy impact test, scanning electron microscopy, and probability theory and statistics. The level of the dispersion was characterized with scanning electron microscopy energy dispersive X-ray spectroscopy analysis. The results showed rather good dispersion of both of inorganic nanofiller, with a mixture of exfoliated and confined morphology. The results indicated that the impact strength of the industrial nanocomposite decreased with the increase of inorganic particulate content. The impact reliability of the industrial nanocomposites depends on the type of nanofillers and their dispersion and distribution in the matrix.

The effect of secondary nanofiller on mechanical properties and formulation optimization of HDPE/nanoclay/nanoCaCO3 hybrid nanocomposites using response surface methodology

“…Evidently, it was deteriorated when compared to the unfilled HDPE. [16] This is predictable since better dispersion of the NC by the addition of nCC occurred in the ternary nanocomposites and consequently, toughening mechanisms were prohibited because of the reduced mobility of HDPE segments. To get a better evaluation of the impact strength, an additional sample consisting of 9 wt% of PE-g-MA and 3 wt% of NC (ie, MA9NC3nCC0) was also prepared under the same processing conditions.…”

“…Additionally, no meaningful changes were detected in the yield strength by increasing the content of nCC, which is in line with previously reported results. [12,16] The alteration in the impact strength of nanocomposites by the variation of nCC loading is depicted in Figure 3C. Evidently, it was deteriorated when compared to the unfilled HDPE.…”

The effect of nanoclay on the nonlinear viscoelastic behavior of high‐density polyethylene

“…This mixing system ensures a good quality homogeneous mixture. [ 8,35 ] The HDPE granules were poured into the Banbury mixer's mixing chamber, and then nanoclay was added to it. After the mixer temperature gradually increased and reached 180°C, the hot mixture was carried to the extruder with a conveyor belt.…”

“…3 Fillers are divided into two categories as functional fillers and cavity fillers (mainly to reduce cost). [28][29][30] Friction modifiers are of particular importance among functional filling materials. Friction modifiers have various roles in increasing or changing friction and mechanical properties.…”
