Summary: Polyamide 66 (PA66) poses a risk of dust explosion during processing and manufacturing, but the addition of melamine poly-phosphate (MPP) can effectively reduce this hazard. The values of maximum explosion pressure, minimum ignition energy, and minimum ignition temperature of PA66 dust were significantly reduced after adding MPP. Furthermore, the thermal pyrolysis behavior of PA66 dust was altered by the addition of MPP, affecting the production of combustible gases and the formation of carbon layer.

Summary: In this study, the addition of nano silicon and piperazine pyrophosphate/melamine polyphosphate into polypropylene was found to improve thermal stability and flame retardancy. The optimal synergistic ratio was determined as 1 wt% SiO2, 10 wt% piperazine pyrophosphate, and 5 wt% melamine polyphosphate. The synergistic mechanism involved the formation of a reactive cross-linking network and a foaming nucleating agent to enhance the carbon protective layer.

Summary: Expandable graphite (EG), aluminum (diethyl)polyphosphinate (AlPi), and melamine polyphosphate (MPP) were used as flame retardant multi-material additives in a polyamide 6 (PA6) matrix. The study found that there was a synergistic effect between EG and AlPi/MPP, leading to an increase in oxygen index and mechanical residue stability. The synergy was attributed to the CO2 evolution during decomposition stages and the solid decomposition products of AlPi/MPP acting as glue between expanded graphite.

Summary: Natural polysaccharides, such as sodium alginate (SA), have attracted attention for their inherent flame retardancy, biodegradability, and environmental friendliness. In this study, flame retardant poly(vinyl alcohol) (FR-PVA) composites containing ammonium polyphosphate (APP) and SA were produced, exhibiting excellent fire retardance and self-extinguishing properties. SA not only inhibits the agglomeration of APP, but also enhances flame retardancy by promoting the formation of char carbon. The resulting FR-PVA composites have potential applications in packaging, home textiles, and biomaterials.

Summary: This paper evaluates the abrasion resistance of a carbon fiber composite filled with layered-silicate clay nanoparticles. The study investigates the dispersion and performance of the clay-epoxy nanocomposite, and determines the optimal content for fiber composite production. The nanocomposite mixture is prepared by dispersing clay nanoparticles in the epoxy monomer, followed by vacuum infusion to produce the fiber reinforced composite. The presence of nanoclay reduces weight loss and damage on the impacted surface.

Summary: This study investigates the use of melamine cyanurate (MCA) and graphitic carbon nitride surface treatment to improve the flame retardant properties of nylon 56. The modified MCA (CNMCA) showed improved dispersion in the PA56 matrix and achieved a UL94 V-0 rating and a limiting oxygen index (LOI) value of 30.1%. The addition of CNMCA resulted in a significant reduction in the total heat release rate (THR) and total smoke release (TSR) of PA56.

Summary: In this study, colorless and transparent polyimide (PI) nanocomposite films were synthesized by dispersing organoclay in poly(amic acid) through a solution intercalation method. The thermomechanical properties and morphology of the films were investigated with different content of organoclay. It was found that the film with a 0.50 wt% organoclay content exhibited the best physical properties, while the properties deteriorated when the organoclay content exceeded a critical content.

Summary: A melamine vapor-derived method is developed to fabricate UiO-66@g-C3N4, which exhibits improved photocatalytic performance for tetracycline degradation compared to pristine UiO-66. This enhancement is attributed to the desirable textural and chemical properties of UiO-66@g-C3N4 derived from melamine vapor synthesis.

Summary: In order to prepare g-C3N4 with enhanced photocatalytic activity for tetracycline (TC) removal, KCl was utilized in different mixing conditions with precursors, resulting in the formation of KCl-incorporated heptazine-rich g-C3N4. The improved activity can be attributed to enhanced charge separation, nanojunction formation, and increased number of photoexcited electrons. Further optimization of the KCl mixing conditions and precursor ratio can lead to more effective TC removal through photocatalysis.

Summary: This article proposes a method using supercritical carbon dioxide (scCO(2)) to obtain compostable bionanocomposite foams based on PLA and organoclay. The foams showed a closed cell and uniform cell structure with enhanced thermal stability and improved overall mechanical performance. The water uptake behavior demonstrated that the foams had low water absorption, and they also disintegrated under composting conditions. Therefore, these bionanocomposite foams seem to be a promising sustainable alternative for applications such as food packaging.

Summary: This study investigated the properties of OMMT filled EVA/NBR nanocomposites, finding that an increase in gel content can enhance the elastic modulus and yield stress, while decreasing the strain-at-break. Moreover, the tensile strength and modulus exponentially increased with strain, but the energy-at-break decreased with gel content. Additionally, changes in relaxation time and crystalline peak intensity ratio were observed with increasing gel content in the materials' structure and rheological behavior.
