A novel route towards halogen-free fire retardancy of polymers through innovative surface coating is described. Nanofibre mats based on polyimide are deposited on PA66 through electrospinning. Scanning electron microscopy (SEM) is used to characterize the nanofibres. Cone calorimeter tests were performed to evaluate the fire performance. Due to their low thermal conductivity, electrospun nanofibre mats act not only as sacrificial layers, but also as a protective surface that delays ignition. The effect is influenced by the fibre diameters and the imidization.
