Abstract

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
