“…25 Furthermore, filler-filler and filler-rubber interactions influence torque differences. 42 As depicted in Figure 4d, M H -M L values of ENR-50 nanocomposites were higher than for ENR-25 nanocomposites. This may be attributed to a higher viscosity of ENR-50 as compared with ENR-25 nanocomposites.…”

In this study, cerium oxide nanoparticles (nanoceria, CeNP) were used as a nanofiller in epoxidized natural rubber with varying epoxide levels, including 25% epoxidation (ENR‐25) and 50% epoxidation (ENR‐50). Co‐precipitation methods were employed to synthesize a pure phase of CeNP with an average particle size of 11.4 ± 2.0 nm. CeNP was characterized using X‐ray diffraction (XRD), transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy. The effect of CeNP loading with 0–3 parts per hundreds of rubber (phr) on the properties of rubber nanocomposites was explored. ENR‐25 nanocomposites with 1 phr of CeNP exhibited higher tensile strength and elongation at break compared to ENR‐50 nanocomposites. These findings correspond to a lower Payne effect, improved scorch safety, and better processability. The strongest and most effective CeO2–ENR interactions via silane linkages are expected to outperform sulfur crosslinking in ENR‐25 having 1 phr of CeNP. Microstructural evaluation of an ENR‐25 sample containing 1 phr of CeNP indicated well‐distributed nanofillers in the ENR‐25 matrix, indicating that CeNP and ENR‐25 appeared to be well‐matched. Hardness of all ENR nanocomposites increased with CeNP loading. The cracking resistance, creep properties, and thermal stability of rubber nanocomposites were unaffected by addition of CeNP in the ENR‐25 and ENR‐50 samples.

Cellulose fibers were modified via aqueous silane‐graphene oxide (GO) coordination by flash drying and extrusion dispersion process. The adsorption of GO reduced the polarity of the cellulose fiber surface and attenuated the agglomeration effect between the cellulose fibers, thus facilitating the dispersion of fibers in the rubber matrix. Adding aqueous 3‐aminopropylsilane oligomer (8150) incorporated active sites on the surface of cellulose fibers, thereby improving the interfacial binding properties of cellulose nano fibers (CNFs) and natural rubber (NR). After blending the modified CNFs with NR latex, high‐temperature flocculation was performed using an atomised flash device. Finally, CNF/NR was pre‐dispersed through a twin‐screw extruder, after which a CNF/NR masterbatch with excellent performance was prepared. Experimental results revealed that composites prepared using GO‐8150 via the flash drying‐twin‐screw dispersion process exhibited excellent dispersion characteristics, processing properties, mechanical properties, rolling resistance, wear resistance, and heat generation properties. Compared with traditional dry mixing, the composites prepared by flash drying‐twin‐screw dispersion process showed a 16.95% increase in tensile strength, 16.07% increase in 300% constant elongation, 19.01% reduction in abrasion consumption, 42.26% reduction in rolling resistance, and a reduction in the Payne effect. This study offers an efficient and environmentally friendly method for the high‐value utilization of natural fibers and the preparation of NR composites with excellent properties, while providing a green and nonpolluting modification process with no acidic liquid discharge.Highlights GO‐8150 reduces the polarity of the fibers and promotes dispersion. The flash extrusion dispersion process achieves green flocculation. 42% lower rolling resistance for rubber composites.

Modifying natural rubber latex (NRL) and blending it with NRL can improve NRL performance and expand application elds. The performance of co-blended latex will change due to changes in non-rubber components during storage. Therefore, it is important to study the change of properties during the storage of co-blended latexes. In this paper, 30% methyl methacrylate grafted natural rubber (MG30) was synthesized by cumene hydroperoxide/ tetraethylenepentamine (CHPO/TEPA) initiating system, MG30 and NRL were mixed in different proportions to study the morphology and physical and mechanical properties, and the colloidal properties and emulsion properties of co-blended latexes were studied during storage. The results showed that the mechanical stability of NRL and co-blended latexes were high and the viscosity gradually increased during storage. The study of the vulcanization characteristics of the coblended latexes lms and the physical and mechanical properties of the vulcanized latex lms showed that the vulcanization time of the co-blended lms increased and the torque value increased in comparison to NRL. With the increase of MG30 content, the tensile strength and tear strength of the coblended latexes vulcanized lms showed a trend of increasing and then decreasing, and the co-blended lm with 10% MG30 showed the best mechanical properties.
