Sulfur Diffusion Studies Imitating Recycled Ground-Rubber-Containing Compounds.
Polymers (Basel)
November 2024
Elastomer Technology and Engineering (ETE), University of Twente, 7522 NB Enschede, The Netherlands.
In-rubber properties of vulcanizates deteriorate in the presence of incorporated recycled ground rubber (GR). This behavior is partly explained by a possible diffusion of sulfur from the rubber matrix into the GR. Therefore, the sulfur concentration and, thus, the crosslink density in the matrix are reduced.

Article Synopsis
- Nanocomposites using natural rubber (NR) and organomodified montmorillonite (MMT) nanoparticles were created with two types of polyoxazolines as surface modifiers.
- Characterization techniques like X-ray diffraction and transmission electronic microscopy showed that the addition of nanofillers notably improved mechanical properties, specifically tensile strength and elongation at break, especially in composites containing carbon blacks.
- Among the two surface modifiers tested, poly(2-ethyl-2-oxazoline) was found to be the most effective for modifying MMT, making it a promising additive for tyre treads that balances fuel efficiency and driving safety.
Composites Based on Eucalyptus Nitens Leaves and Natural Rubber as a Valuable Alternative for the Development of Elastomeric Materials with Low Microbiological Impact.

The forest industry produces several low-value by-products, such as bark, sawdust, limbs, and leaves, that are not ultimately disposed of and remain in the forests and sawmill facilities. Among these by-products are leaves, which contain not only cellulose fibers and lignin but also essential oils such as terpenes. These are biosynthesized in a similar way as cis-1,4-polyisoprene.

The inclusion of sacrificial hydrogen bonds is crucial for advancing high-performance rubber materials. However, the molecular mechanisms governing the impact of these bonds on material properties remain unclear, hindering progress in advanced rubber material research. This study employed all-atom molecular dynamics simulations to thoroughly investigate how hydrogen bonds affect the structure, dynamics, mechanics, and linear viscoelasticity of rubber materials.

Eucommia ulmoides rubber (EUR) is a high-quality natural rubber resource, which can be extracted from different organs of the Eucommia ulmoides tree. In this study, EUR was isolated from the leaves, barks, and pericarps, and the structural characteristics and physicochemical properties of EUR were systematically determined. The accumulation and distribution of EUR in different tissues were assessed through in situ observations combined with cellular and subcellular scales.
