Abstract

Highlights

A superelastic and washable sponge based on biomimetic spring-like helical micro/nanofibers is directly fabricated by multiple-jet electrospinning technology.
The resulting sponge exhibits both lightweight (low density of 7.1 mg cm^–3) and robust mechanical property (large tensile strain up to 200%).
The sponge also shows efficient thermal insulation performance with low thermal conductivity (24.85 mW m^–1 K^–1), and remains structural stability even after cyclic washing, making it a promising candidate for personal protection in cold environments.

基于仿生螺旋纤维的超弹性可洗微/纳米纤维海绵的高效保温

利用多喷嘴静电纺丝技术直接制备了一种基于仿生弹簧状螺旋微纳米纤维的超弹性可洗海绵。由此产生的海绵具有重量轻（低密度为7.1 mg cm-3）和坚固的机械性能（大拉伸应变高达200%）。该海绵还具有低导热系数（24.85 mW m-1 K-1）的高效隔热性能，即使在循环洗涤后仍保持结构稳定性，使其成为寒冷环境中个人防护的有希望的候选者。

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.
