Highlights The as-fabricated waterborne polyurethane (WPU) nanocomposite film exhibits a 55.6% improvement in limiting oxygen index, 66.0% and 40.5% reductions in peak heat release rate and total heat release, respectively, and 93.3% increase in tensile strength relative to pure WPU film. The resultant WPU nanocomposite film presents a high thermal conductivity (λ) of 12.7 W m−1 K−1 and a low dielectric constant (ε) of 2.92 at 106 Hz.
