Abstract

Highlights

Using electrospun high-strength carbon nanofibers as the aerogel scaffold, high loading of polyaniline in the aerogel was achieved through seed polymerization, forming the core–shell structure fibers and simultaneously connecting the fibers as a stable conductive network.
Combining carbon-based materials with conductive polymers like polyaniline significantly improves shielding performance, achieving electromagnetic interference shielding efficiency of up to 84.5 dB and SE d⁻¹ values greater than 791.2 dB cm³ g⁻¹. Flame retardancy reduces PHRR by 65.8%, and thermal insulation with low thermal conductivity of 0.104 W m⁻¹ K⁻¹.

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.
