摘要

由于机械脆性和较差的弹性，气凝胶的实用性受到不利的限制。为了应对这些挑战，Pang等人发表在《科学》杂志上的一项研究提供了一类穹顶细胞气凝胶，这些气凝胶在很宽的温度范围内表现出超弹性：从液氦温度（4.2 K）到2273 K，以及出色的绝热性和化学通用性。这项工作重新定义了气凝胶材料在极端条件下的可能性，为开发在超高温下具有超弹性和超低导热性的先进气凝胶提供了新的范例。

Aerogels with ultrahigh-temperature super elasticity

The practicality of aerogels is adversely restricted with mechanical brittleness and poor elasticity. To address these challenges, a study published in Science by Pang et al. provides a class of dome-celled aerogels that exhibit super elasticity across a wide temperature range: from liquid helium temperatures (4.2 K) to a 2273 K as well as remarkable thermal insulation and chemical versatility. This work redefines what’s possible for aerogel materials under extreme conditions, offering a new paradigm to develop advanced aerogels with super elasticity and ultralow thermal conductivity at ultra-high temperature.
