Summary: By adding Sasobit, ESO, and Sasobit/ESO composite to reduce the preparation temperatures of SBRMA mixture, it was found that the Sasobit/ESO composite not only has better lowering effects on temperatures, but also enhances the high- and low-temperature performance of SBRMA, mitigating the adverse impacts of aging on its performance.

Summary: Magnetorheological elastomers (MRE) have the ability to change stiffness by applying a magnetic field. Thermoplastic elastomers (TPE) have been investigated as matrix material, while different surface treatments of carbonyl iron particles (CIPs) as filler affect the performance. The MR effect under static and dynamic load shows significant results.

Summary: The demand for multifunctional, transparent epoxy resin with superior dielectric, mechanical, and fire-safety performances is increasing in modern industries. Researchers have developed an epoxidized, phosphaphenanthrene-containing poly(styrene butadiene styrene) (ESD) for advanced fire-safe epoxy resin, which maintains high transparency and improves UV-blocking property. The addition of 10 wt% ESD results in improved mechanical properties, decreased dielectric constant and loss, and outperformance compared to other fire-safe epoxy resins. This research provides an effective method for developing multifunctional flame-retardant epoxy resin.

Summary: Flexible bio-based polymeric materials were produced by combining epoxidized soybean oil, aqueous citric acid solutions, and varying amounts of epoxidized oleic acid. The stiffness of the materials increased with decreasing content of epoxidized oleic acid, as determined by tensile testing.

Summary: Formaldehyde-free epoxidized soybean oil-based resin was synthesized under acidic conditions using agricultural and forestry sources as raw materials. A bio-based grinding wheel was fabricated by formulating the resin with wood powder. The resulting grinding wheel showed a smooth surface, high hardness, and wear resistance, with over 90% of its raw materials being renewable biomass. This approach has the potential to replace commonly used petrochemical resins in grinding wheel fabrication.

Summary: The high-performance thermoplastic elastomers (ZASM/SEBS composites) were prepared by blending 3-Amino-1,2,4-triazole, SEBS-g-MA, zinc acetate, and SEBS successively, showing excellent mechanical strength-toughness combination. The mechanical performance of the composites was investigated by tensile test, demonstrating that with decreasing ZASM ratio, tensile strength and elongation at break first increased and then decreased, with the best performance achieved at 30% ZASM ratio.

Summary: This study resolves the poor high-temperature performance and lower dissolution of styrene-butadiene-styrene (SBS) modified asphalt and soybean bio-asphalt (SBA) by using tannic acid modified bamboo fiber. The results showed that the addition of bamboo fiber and waste soybean oil-extracted bio-asphalt can significantly enhance the rheological properties of the modified asphalt.

Summary: RP-AESO porous materials prepared by emulsion template have uniform pore size distribution, hydrophobic properties, and oil absorption capacity. With increasing concentration of H-ESO-HEC, the pore density of RP-AESO porous materials increases and the average pore size decreases, leading to a decrease in compressive strength. Furthermore, these porous materials exhibit good reusability.

Summary: A novel silica reinforced epoxidized SSBR/epoxidized BR nanocomposite (S-ESSBR/EBR) without using silane coupling agent (SCA) was prepared in this study. ESSBR and EBR with different epoxidation degree were synthesized using oxidant H2O2 and reaction-controlled phase-transfer catalyst CPC-PW4O16. The distribution of silica in two phases became homogeneous by transferring silica nanoparticles from ESSBR phase to EBR phase with increasing epoxidation degree of EBR. The S-ESSBR/EBR nanocomposite showed high wet skid resistance, low rolling resistance, and excellent abrasion resistance as green tire tread.

Summary: Bio-based flame retardants were used to reduce the flammability of ABS, achieving comparable results to commercial brominated ABS. The best-performing compositions significantly lowered ABS's peak heat release rates, but also led to an increase in modulus and a loss in toughness. Synergistic interactions between the FRs and ABS matrix, as well as between different FR components, were found to be responsible for the reduced flammability.

Summary: Design and synthesis of degradable bio-based thermosets from epoxidized soybean oil (ESO) via ring-opening metathesis polymerization (ROMP) were carried out. The ESO-based thermosets showed promising thermal and mechanical properties, were suitable for composite fabrication, and could be fully degraded under aqueous NaOH or KOH. The functionalized ESO also exhibited copolymerization capabilities with norbornene, forming partially degradable copolymers. This approach offers potential for the synthesis of degradable vegetable oil-based thermosets for various applications and environmental sustainability.
