Summary: In this study, ammonium polyphosphate (APP) was coated on the surface of ramie fabrics (RFs) to obtain flame-retardant RF reinforced epoxy resin composites. The flameretardant composites achieved a limiting oxygen index of 33.8% and UL-94 V-0 rating when the weight gain rate of APP in RFs was about 20%. Additionally, the flame-retardant composites showed reduced peak heat release rate, total heat release values, and smoke production. However, the presence of APP had a negative effect on the internal compatibility and mechanical properties of the composites.

Summary: A bio-based vinyl ester resin monomer was prepared and used to overcome the flammability and smoke release issues of vinyl ester resin. The impact of a diluent on the properties of the resin and its fiberglass-reinforced composites was investigated. The results showed that the bio-based resin and its composites had higher glass transition temperatures and improved mechanical properties compared to the conventional resin. Additionally, the bio-based resin exhibited superior flame retardancy and smoke suppression due to its better wettability on fiberglass.

Summary: In this study, a bio-derived core-shell flame retardant (CSFR) was applied to improve the flame retardancy of polylactide (PLA) while maintaining its environmentally friendly profile. However, the enhancing effect of the CSFR on the mechanical properties of PLA was limited, and even caused a deterioration in rigidity. Therefore, functionalized graphene oxide (GO) was used to improve both the flame retardancy and mechanical properties of PLA. The combined effect of CSFR and GO resulted in PLA with better thermal and mechanical properties.

Summary: The study demonstrated that DA-APP as a flame retardant for TPU significantly improved the flame retardancy of TPU composites, reducing the risk of fire and decreasing smoke and heat release. The key mechanism for this enhancement was the promotion of TPU to produce water and carbon dioxide by DA-APP, diluting the oxygen concentration, and the formation of a dense carbon layer isolating heat and oxygen.

Summary: Polyurethane foams (PUF) are a main cause of urban fires, but incorporating flame retardants severely affects their mechanical properties. This study presents a simple method to fabricate phosphorus-containing multiscale energy dissipation networks (PMNs) to improve the toughness and fire safety of PUF. The unique PMNs facilitate stress redistribution and dissipation, allowing PUF to sustain large deformations and achieve increased fracture strength, elongation at break, and toughness. The PMNs also show better flame retardant performance compared to other phosphorus-containing species.

The incorporation of a sidechain caged structure enhanced chain entanglement, leading to improved mechanical strength and heat resistance. Additionally, the flame retardancy of the polymers was significantly enhanced due to the free radical scavenging effect of the phosphorus-based monomer. This work provides a novel method for fabricating high-performance polymers for various applications.

Summary: By incorporating a P/Cu-hybrid silica aerogel, we propose a new approach for thermal insulation, flame retardancy, smoke suppression, and reinforcement of polyurethane foams. The hybrid aerogel combines the carbon-promoting action of P, catalytic attenuation of Cu, and the barrier effect of aerogels, resulting in high smoke-suppressing and flame-retardant efficiency. The aerogel-containing composite foam exhibits a special hierarchical porous structure, which enables lower thermal conductivity and higher thermal insulation than pure RPUF.

Summary: This study proposes a unique structural design strategy that combines a hollow structure with gradient hierarchical heterostructures to achieve high-performance microwave absorption. MoS2 nanosheets are grown uniformly onto the double-layered Ti3C2Tx MXene@rGO hollow microspheres. The gradient hierarchical heterostructures, including a MoS2 impedance matching layer, a reduced graphene oxide (rGO) lossy layer, and a Ti3C2Tx MXene reflective layer, have demonstrated significant improvements in impedance matching and attenuation capabilities. Additionally, the incorporation of a hollow structure can further improve microwave absorption while reducing the overall composite density. This work provides an exquisite perspective on heterostructure engineering design for developing next-generation microwave absorbers.

Summary: This study demonstrates a smart-puffing transparent flexible phosphite-protonated siloxane (PSiP) material that exhibits excellent fire protection, high-temperature insulation, antibacterial, antimold, and self-healing properties. A one-step method is developed to create microporous PSiP using (3-aminopropyl)triethoxysilane and phosphite via hydrophilic-hydrophobic interaction-driven self-assembly. PSiP employs an intelligent thermal-responsive self-puffing behavior to achieve high-temperature insulation, effectively blocking 87.8% of 1400°C heat. The unique dynamic phosphite-protonated siloxane network in PSiP with high transparency affords self-healing ability as well as potent defense against fire and bacteria. This finding opens up a new avenue for developing transparent, flexible, and high-performance multihazard protective materials with potential applications in buildings, windshields, electronics, and beyond.

Summary: This paper investigates the tool-ply friction behavior of jute/PLA biocomposites in thermoforming. A pull-through friction testing device was developed to characterize the tool-ply friction behavior of jute/PLA prepreg at elevated temperature. The effects of alkali treatment, fiber orientation, normal force, and slipping velocity were studied, and a quantitative definition of tool-ply friction behavior was achieved. The results indicate a strong relationship between tool-ply friction behavior and woven and fiber structures, indicating hydrodynamic lubrication.
