Abstract Intumescent flame‐retardant coatings offer excellent passive fire protection for flammable materials and steel. However, a key challenge is the conflict between increased melt viscosity from additive catalyst chemical foaming behavior. Herein, “interfacial autocatalytic” strategy‐guided design of double dopant‐free epoxy coating reported with 100 µm boron‐rich upper layer 300 phosphorus‐rich bottom layer. This generates BPO 4 in situ at interface during combustion, synergistically catalyzing charcoal formation expansion process. , its better lattice arrangement, able to form dense ceramic 5.5 stack 10–40 nm nanoparticles, encapsulating an underlying 1.8 cm intumescent char The demonstrates superior thermal insulation heat‐resistant time up 50 min, 271% delay ignition time, ultra‐low growth rate 58% reduction, 33% reduction total heat release. In addition high transparency, this presents easy self‐healing, good mechanical properties, water resistance. autocatalytic strategy confined space‐time introduces new method enhancing catalytic charring flame retardancy.

ABSTRACT High thermal conductivity and high flame‐retardant charring properties can meet the technical requirements for fire safety of polycarbonate (PC) used in 5G high‐frequency devices. In this study, a novel aluminum maleimide phosphinate (NBAP) with ideal fire‐retardant was synthesized, synergistic system flame retardant comprising boron nitride (BN) NBAP developed. 3%NBAP/20%BN/PC obtain outstanding retardancy 37.6% LOI values UL 94 V‐0 rating vertical burning test; sample also 231 kW/m 2 PHRR, 33.9 MJ/m THR, 11.2 m TSP. The results were much lower than neat PC. This result attributed to excellent effect BN, which obtained barrier condensed phase. terms conductivity, containing metallic ions promotes enhancement PC combined lamellar BN build an pathway, thus effectively increasing by 4.57 times compared word, study provide significant exploration constructing high‐performance composites retardance heat conduction.
