Abstract
Official abstract text for this publication.
A low-density polyethylene nanocomposite comprising 5 weight percent or more of at least one nanoscale filler selected from the group consisting of montmorillonite clay, silica and zinc oxide. Changes in weatherability of the three low-density polyethylene nanocomposites based on the nanoscale fillers are determined. A surface area of the nanoscale filler in the nanocomposites is from 10 m 2 /g to 50 m 2 /g.
First claim
Opening claim text (preview).
The invention claimed is: 1. A smectite clay based low-density polyethylene nanocomposite in the form of pellets, consisting of a low-density polyethylene resin having a melt index of 0.8 to 1.2 g/10 minutes (190° Celsius, 2.16 kg), and 5 weight % or more of a nanoscale montmorillonite clay modified with a quaternary ammonium salt and having a specific surface area of 10 m 2 /g to 50 m 2 /g. 2. The nanocomposite of claim 1 , further comprising nanoscale silica. 3. The nanocomposite of claim 1 , further comprising nanoscale zinc oxide. 4. The nanocomposite of claim 1 , wherein the montmorillonite clay has an agglomerate size of about 8 μm. 5. The nanocomposite of claim 1 , wherein the montmorillonite clay is composed of individual platelets having a thickness of about 1 nm, an aspect ratio of greater than 50, and an interlayer spacing, determined by XRD, is about 2.52 nm. 6. The nanocomposite of claim 2 , wherein the quaternary ammonium salt is N,N-dimethyl dehydrogenated tallow quaternary ammonium chloride.
