“…The stabilization effect of TiO 2 increases with increased loading. The effect of TiO 2 upon durability of polymer is also affected by the photo reactivity of pigment such as the least photo reactive pigment leads to a high degree of stabilization . Recently, Rasouli and coworkers have reported enhanced weathering stability of wood‐HDPE composite by addition of ZnO .…”

Natural weathering of high-density polyethylene (HDPE) and its graphene nanocomposites was studied. The nanocomposites, prepared by in situ polymerization of ethylene, were exposed to the natural environment for 30, 60, and 90 days. The effects of weathering on the crystallinity, melting temperature, and lamellar thickness distribution were studied using differential scanning calorimetry. The changes in chain microstructure and molecular weight were determined by crystallization analysis fractionation and gel permeation chromatography, respectively. The effects of weathering on the dynamic mechanical properties and the morphology of the nanocomposite were also determined. The parent HDPE suffered severe degradation as expected. However, graphene-reinforced HDPE nanocomposites show resistance to degradation. The changes in the crystallinity, lamellar thickness, molecular weight, and dynamic mechanical properties of graphene nanocomposites were less pronounced as compared to the parent HDPE.

“…In 1977, Sorvik and coworkers used titanium dioxide (TiO 2 ) as a heterogeneous catalyst to oxidatively degrade low-density PE at 150 °C. 99 They witnessed the yellow coloration of polymers, indicating oxidative degradation. Hinge and coworkers published a recent example in 2020, in which they studied the stability of poly(acrylonitrile–butadiene–styrene) (ABS) blended with an Fe or Cu-based pigment at 60 °C for 1440 h. 100 The impact toughness of ABS decreased by up to a factor of four compared to the absence of heterogenous pigment.…”

In the present study the effect of metal poisoning was studied in a natural rubber (NR)-based tiretread compound. The experimental compound contained 1000 ppm copper metal as an additional ingredient. A detailed study was carried out and the results of the experimental compound were compared against a control compound having no metal ion. The effect of metal poisoning was not significant in the case of the green experimental compound, even after prolonged storage of 150 days. However, the cured experimental compound deteriorated substantially after ageing in aerobic-, anaerobic-, oil-, and outdoor-ageing conditions. The ozone resistance property of the experimental compound also proved to be inferior. The degradation kinetic of metal poisoning was found to be a first-order reaction and the service life (as expressed by the half-life period) was drastically reduced for the poisoned compound.
