Abstract

• Multifunctional core-shell fiber films were prepared by one-step coaxial electrospinning technique. • Efficient halogen-free synergistic intumescent flame retardant system. • Films exhibit superior phase-change enthalpy, shape stability and flame retardant properties. • Core-shell dual functionality enables simultaneous thermal regulation and flame retardancy for fabrics and lithium-ion battery separators. Phase change materials (PCMs) like PEG-4000 offer high heat storage density and can isothermally store or release energy. However, there are fatal safety problems, such as leakage and flammability during transition, which greatly limit the practical application. To address these issues, coaxial…
