摘要

采用电纺高强纳米碳纤维作为气凝胶支架，通过种子聚合实现了聚苯胺在气凝胶中的高负载，形成了核壳结构纤维，同时将纤维连接成稳定的导电网络。碳基材料与聚苯胺等导电聚合物结合，显著提高了屏蔽性能，电磁干扰屏蔽效率高达84.5 dB， SE d−1大于791.2 dB cm3 g - 1。阻燃性使PHRR降低65.8%，保温导热系数为0.104 W m - 1 K - 1。

Carbon Nanofiber/Polyaniline Composite Aerogel with Excellent Electromagnetic Interference Shielding, Low Thermal Conductivity, and Extremely Low Heat Release

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.
