Summary: This study investigated the effect of adding flame retardant on the impregnation quality of prepreg tape. By adding high-flow polypropylene to improve the melt viscosity of flame-retardant-modified polypropylene, continuous glass-fiber-reinforced polypropylene flame-retardant prepreg tape was successfully prepared. The tests showed that adding 25 wt% intumescent flame retardant (IFR) achieved the best flame retardancy grade.

Summary: A novel flame retardant (POCODA) synthesized from POC and ODA was investigated for its effects on the thermal stability and combustion behavior of poly(L-lactic acid) (PLA) composites. The addition of POCODA/APP as a synergistic flame retardant showed improvements in the flame retardancy of PLA-based composites, with the optimal ratio achieving a V-0 rating. The proposed mechanism of flame retardance for the PLA/2%POCODA/10%APP composite was discussed based on SEM, TG-IR, and PY-GC/MS measurements.

Summary: This article summarizes the combustion characteristics and flame-retardant mechanism of polyurethane foams, and analyzes the recent progress of different flame-retardant strategies. It also discusses the difference and similarities of combustion behaviors and flame-retardant methods for rigid and flexible polyurethane foams. The article emphasizes the importance of developing efficient flame-retardant molecules or additives, enhancing the durability of flame-retardant coatings, and combining various flame-retardant methods for optimal results. The future development of flame-retardant polyurethane foams should focus on environmental friendliness, high efficiency, high flame-retardant and smoke suppression, and recyclability.

Summary: In this study, a novel intumescent flame retardant Dohor-6000A was used to prepare halogen-free flame retardant PP fibers, with a surface modification to enhance compatibility with the PP resin. The addition of IFR did not damage the crystal structure or orientation of the PP matrix, helping maintain mechanical properties. The presence of IFR significantly improved flame retardant performance and thermal stability of PP fibers, with a LOI value of 29.1% and reduced heat release rates in comparison to pure PP fibers.

Summary: We successfully designed and synthesized high-performance polymers with excellent overall properties by simultaneously modulating their chemical constitution and topological conformation. 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: A novel P-N flame-retardant (PON) was synthesized using diphenyl phosphoryl chloride and piperazine. The thermal stability, combustion behavior, and flame retardancy of PS composites containing PON and different char-forming agents were investigated. The PS/10% PON/10% EG composite exhibited the highest LOI value of 25.8% and significantly reduced pHRR, THR, and TSP compared to neat PS, demonstrating excellent flame retardancy. The flame-retardant mechanism of the composite was discussed based on SEM, TG-IR, and PY-GC/MS analysis.

Summary: In order to enhance the flame-retardant performance of epoxy thermosets while maintaining other properties, a new aromatic imine-containing DOPO-based bisphenol, DOPO-AI, was synthesized. When the mass of DOPO-AI was 25% of DGEBA, the resulting epoxy thermoset EP/20DOPO-AI exhibited excellent flame-retardant properties, showing V-0 rating with a limiting oxygen index of 35.4%. In addition, EP/20DOPO-AI also showed a reduction in heat release and an increase in char-forming ability.

Summary: The study explores the use of a Focal-Plane Array (FPA) imaging system for determining maturity in small cotton fiber bundles. The system was adjusted to examine 140 points per sample, an improvement over the previous study. Results show a strong correlation between FPA and Cottonscope maturity determinations. The FPA IR system is suitable for non-destructively examining and imaging cotton maturity distributions.

Summary: This study examined consumers' acceptance, preference, and willingness to pay for five newly developed convenient catfish products using experimental auction sessions. The research found that the acceptance level for panko-breaded products was higher than marinated products, and consumers preferred breaded products. The participants' age and being African-American catfish consumers were positively associated with their willingness to pay, while holding a bachelor's degree was negatively correlated with willingness to pay.

Summary: Agricultural waste and residues, such as cotton gin trash and cotton gin motes, were used to prepare lignin-containing cellulose nanofibers with gradient degrees of lignin content. The physical properties of the nanofibers were affected by the lignin content and other components, impacting thermal stability and crystallinity. The degree of polymerization was smaller after processing, with differences based on the source material, resulting in slightly different suspension viscoelastic behavior.
