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 copolymer (TDDL) containing lysine, dopamine, triazine was synthesized and used as a charring agent, while ammonium polyphosphate (APP) served as an acid source to improve the flame retardancy of thermoplastic polyurethane (TPU). Tests showed that TPU blends with 8 wt% APP achieved a UL-94 V0 rating and a LOI value of 30.0 vol%, while TPU blends containing 6 wt% APP/TDDL exhibited a UL-94 V0 rating and a LOI of 29.6 vol%, indicating a synergistic effect between TDDL and APP. In addition, TDDL reduced the heat release rate of TPU/APP blend, promoted the formation of a char layer, and suppressed combustible gas and smoke release. Moreover, TPU blends demonstrated better modulus and elongation at break compared to TPU.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
