摘要

3D打印气凝胶具有超低导热系数（15.8 mW m-1 K-1），是极端环境下理想的保温材料（1 cm厚的绿体在300℃下放置30 min后表面温度保持在≈60℃）。超黑二氧化硅-碳气凝胶具有惊人的光吸收特性（高达99.56%），具有快速的蒸发速率（2.25 kg m-2 h-1）和优异的能量转换效率（94.2%）。超黑和超绝缘特性的结合，为热学和光学领域的多功能、高性能应用提供了巨大的潜力。

Three-dimensional Patterning Super-Black Silica-Based Nanocomposite Aerogels

AbstractSection Highlights

The 3D printed aerogel has an ultra-low thermal conductivity (15.8 mW m^–1 K^–1), make it an ideal insulation material in extreme environment (The surface temperature of a 1 cm thickness green body maintained at ≈60 °C after being placed at 300 °C for 30 min).
The super-black silica-carbon aerogel exhibits surprising light absorption feature (as high as 99.56%), and shows rapid evaporation rate (2.25 kg m^-2 h^-1) and excellent energy conversion efficiency (94.2%).
The combination of super-black and super-insulation features, offering immense potential for multifunctional, high-performance applications across thermal and optical domains.

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.
