Summary: The rheological behavior of an epoxidized natural rubber (ENR) nanocomposite containing silica particles was studied using time-resolved mechanical spectroscopy. Two major events were identified: absorption of rubber macromolecules onto silica surface and gelation resulting in changes in rheological behavior. These events were quantified using parameters related to storage and loss modulus components.

Summary: A new strategy is proposed to improve the distribution of silica in rubber blend without using a silane coupling agent. Silica-filled epoxidized SSBR/ENR nanocomposites have better interfacial interaction and improved dispersion of silica compared to silica-filled SSBR/NR nanocomposites with Si75 as the coupling agent. The epoxy groups effectively adjust the phase selective distribution of silica. The S-ESSBR12/ENR18 nanocomposite shows the best performance, increasing wet-skid resistance by 118%, reinforcing index by 38%, abrasion resistance by 40%, and decreasing rolling resistance by 23%. These ecofriendly nanocomposites have potential application in green tire tread production.

Summary: Glycidyl-POSS and trisilanolisooctyl-POSS were used as functional additives in PLA/ENR blends, with Gly-POSS increasing complex viscosity and storage shear modulus, while HO-POSS acted as a plasticizer in the melt. Gly-POSS also shifted the glass transition temperatures of ENR phase to higher values, indicating stronger cross-linking effects.

Summary: By using natural rubber, chitosan, and polyvinyl alcohol as raw materials, biodegradable semi-interpenetrating polymer network (semi-IPN) composites were prepared for sustained-release preparation. A hydrogel loaded with urea was used as the core, while a shell made of the coating material was prepared for slow-release fertilizer. The coating material showed improved mechanical properties, hydrophilicity, and soil water retention, and the slow-release effect was achieved through a combination of drug diffusion and skeleton dissolution.

Summary: This study presents a novel strategy to tailor the phase morphology and interfacial adhesion of the PLA/ENR blend by partially crosslinking ENR with sebacic acid. The partially crosslinked sebacic acid modified ENRs (mENRs) were prepared by mixing ENR with SA and a catalyst. The phase morphology and interfacial adhesion of the PLA/mENR blend were finely tuned by adjusting the crosslinking degree of mENR. The resulting PLA/mENR blend exhibited drastically enhanced toughness compared to neat PLA, following a toughening mechanism of internal mENR cavitation-induced matrix shear yielding and plastic deformation.

Summary: This study investigated the self-healing performance of epoxidized deproteinized natural rubber (EDPNR) and EDPNR/graphene oxide (GO) composites. It was found that the recovery of tensile strength was higher for EDPNR25/GO0.5 and EDPNR25/GO1.0 composites compared to EDPNR50/GO0.5 and EDPNR50/GO1.0 composites. The interdiffusion of epoxidized natural rubber molecules was identified as the key factor affecting the self-healing performance rather than the hydrogen bonds between GO and functional groups on EDPNR molecules.

Summary: This study reports a strengthened biobased epoxidized natural rubber/adipic acid/cellulose nanocrystal (ENR/AA/CNC) composite, in which biobased adipic acid (AA) forms a network with reversible ester bonds with ENR, allowing the composite to rearrange its topology at high temperatures and exhibit reprocessing capabilities. Additionally, the cellulose nanocrystals (CNCs) form hydrogen bonds with ENR chains, enhancing the mechanical performance of the ENR/AA/CNC composite.
