“…Achieving high ame retardancy performance poses challenges when relying on a single ame retardant. Therefore, a common approach is to integrate synergistic ame retardant llers, 6 which include montmorillonite (MMT), 18 layered double hydroxides (LDHs), 19,20 zinc borate (ZB), 21,22 and alginate. 23 Despite their widespread use, these synergistic agents typically contain only one ame-retardant element, leading to reduced ame-retardant efficiency.…”
