Summary: A scalable and blending route using silicone rubber (SR) with different crosslinking temperature compared to EPDM was developed to improve the mechanical properties of EPDM foams. The addition of SR in the pre-crosslinking process of EPDM forms a complete crosslinking network, enhancing the compatibility between EPDM and SR and improving the mechanical properties of EPDM foams. When comparing SR/EPDM foam with traditional EPDM foam, the former shows significantly increased tensile strength and compressive strength at similar foam densities, reaching a maximum tensile strength and compressive strength of 3.58 MPa and 0.59 MPa, respectively.

Summary: This study successfully prepared F-LSR-POSS by using POSS-V as a chemical crosslinking agent. Various testing methods such as FT-IR, H-1-NMR, SEM, and XRD confirmed the uniform dispersion of POSS-V in F-LSR-POSS. The mechanical strength and crosslinking density of F-LSR-POSS were determined using UTM and DMA, respectively, showing a significant improvement in heat resistance compared to conventional F-LSR. The introduction of POSS-V as a chemical crosslinking agent overcame the poor heat resistance of F-LSR.

Summary: High-efficiency and energy-saving conversion of epoxy thermosets into high value, high quality, and high-performance products is desired for environmental protection and resource utilization. A new strategy for mild degradation of epoxy thermosets and in situ preparation of polyurethane foam from degradation solutions is demonstrated. The degradation solution contains unreacted solvent polyethylene glycol and polyol degradation products, which can react with isocyanate to produce polyurethane. The use of an insoluble catalyst enables in-situ foaming of the degradation solution, allowing for direct and full utilization of degradation products. The rigid epoxy skeleton of the degradation products contributes to the high mechanical properties, thermal insulation performance, low water absorption, regular pore structure, and thermal stability of the obtained polyurethane foam, making it a promising candidate for building insulation materials.

Summary: The study isolated foaming fractions from spent coffee grounds to investigate their foam properties. Results showed that a high molecular weight foaming fraction from defatted robusta spent coffee grounds exhibited higher surface activity, comparable foam stability, and greater foamability than synthetic surfactants. Additionally, coffee oil was found to act as an antifoam agent by retarding the foam-forming and stabilizing activities of both spent coffee grounds-based and synthetic foaming agents.

Summary: Thermoplastic polyether ester elastomer (TPEE) foams were studied in this research, focusing on the effect of chain entanglement on mechanical properties, viscoelasticity, and CO2-foaming behavior. It was found that samples with stronger chain entanglement exhibited increased rigidity and reduced ductility, along with improved linear and nonlinear viscoelasticity. Additionally, the modified TPEE samples showed a higher expansion ratio and a wider foaming temperature window during the CO2-foaming process.

Summary: In this study, the effects of crude oil viscosity and wax precipitation on foaming characteristics were investigated using the depressurization method. The results showed that the foamability of crude oil tends to decrease with increasing temperature below the wax appearance temperature (WAT). However, above the WAT, the foamability weakens drastically and remains relatively constant with temperature. The dominant factor affecting foamability was found to be the temperature-induced change in oil phase viscosity. Additionally, the foam stability decreased significantly with increasing temperature, which was attributed to the decrease in interfacial dilational modulus and the weakened film strength at the crude oil-CO2 interface.
