“…The key objective of compounding is concerned with securing an optimum balance between the three significant characteristics, namely cost, processability and final vulcanizate properties. The established ingredients of tyre tread consist of synthetic rubbers [ 62 ], petroleum-based fillers [ 63 ] performance modifiers [ 64 ], processing aids, [ 65 ] etc. The majority of the ingredients are synthetic materials with non-environmentally friendly backgrounds and output characteristics.…”

Growing natural calamities as a consequence of global warming are one of the most pondering subjects today. The exponential growth of environmental pollution due to unscientific human exploitation of natural resources is considered the prime reason for the harsh responses of nature. Researchers from various fields of industry and academia are working hard to develop and implement products/technologies that are environmentally friendly or less harmful to the ecosystem. Material researchers, specifically those working in the automobile sector are also not behind in search of green products from eco-friendly raw materials and production methods. The automobile industry is collectively responsible for around 40% of global pollution in terms of greenhouse gas emissions. Out of which around 20–30% is originating from tyre production and its end-use. In this view, tyre production from eco-friendly raw materials and technologies that have minimum hazardousness to the environment is a hot research topic today. A few products in the market with “green” tags and many are in the pipeline for the recent future. This review summarises a detailed discussion of the emerging green technologies for tyre production and depicted comprehensive data from the available literature. The paper has been drafted from a well-balanced academic and industrial point of view since the researchers from both sectors are working in harmony for a better future for green tyre technology.

The development of ultrahigh molecular weight polyethylene (UPE) has been restricted due to its linear structure and low thermal conductivity. In this paper, graphene oxide (GO) was prepared by the modified Hummers method, and then UPE/reduced graphene oxide (rGO) powder was prepared by reduction with hydrazine hydrate. UPE/natural graphite (NG), UPE/carbon nanofiber (CNF), and UPE/rGO are prepared by hot compression molding. With the increase of thermally conductive fillers, the high density of the composite makes the thermal conductivity of the crystal structure more regular and the thermal conductivity path increases accordingly. Both TGA and SEM confirmed the uniform dispersion of carbon filler in epoxy resin. Among the three composites, UPE/NG has the best thermal conductivity. When the NG filling content is 60 phr, the thermal conductivity of the UPE/NG composite is 3.257 W/(mK), outperforming UPE/CNFs (0.778 W/(mK) and pure UPE (0.496 W/(mK) by 318.64 and 556.65%, respectively. UPE/CNFs have the best dielectric properties. Comparison of various carbon fillers can provide some references for UPE’s thermal management applications.

Carbon Nanospheres (CNs) are nano-carbon materials. In order to expand their application fields, this study applies them to rubber fillers. In this study, CNs were prepared by vapor deposition method in a high temperature tube furnace. After acidification of CNs, ZnO was grown in situ on the surface of CNs. CNs@ZnO/NR composite was prepared by traditional mechanical blending method. The experimental results showed that the ZnO nanoparticles were adsorbed on the surface of CNs, resulting in a strong interfacial interaction with the CNs. In the composite material, the hybrid is uniformly dispersed in the rubber matrix under the influence of its own many factors, thereby improving the cross-linking effect of the composite material. Compared with the ZnO/NR composite, the modulus at 100%, 200%, and 300% elongation of NR composites are increased by 40.3%, 30.6%, 23.3%, and 9.6% respectively, maintaining the elongation at break of the composites. At the same time, the rigidity of the composite material is increased, the cross-linking efficiency is improved, and the crosslinking density of the composite material is greatly improved. Compared with ZnO C /NR composite, CNs@ZnO/NR composite maintained better wet-skid properties. The CNs in the CNs@ZnO can inhibit the agglomeration of ZnO nanoparticles, which can better improve the vulcanization rate and crosslinking density, and is an efficient vulcanization activator. This study provides a simple synthetic route for ZnO nanofillers for the preparation of high-performance natural rubber composites.
