随着人类继续探索更苛刻和更不可预测的设置,为特定用例设计的工具是不够的。此外,用于海洋学的测量船和用于行星探索的航天器空间有限,因此必须根据设备的适应性和多功能性来确定设备的优先次序。为海洋和太空探索而开发的工具是故意非专业化的。一个真正实用的发明需要一种单一的材料,可以塑造出许多不同的属性。在资源稀缺的环境中,它还必须是可重复使用的。想象一下,一名宇航员通过将单一材料转换为扳手,粘合剂和补丁来修复火星车上的车轮。在本期的第545页,Boynton等人报道了一类具有可逆的、温度可编程的机械性能的聚合物材料,这些材料可以在这种情况下设想。
As humans continue to explore harsher and less predictable settings, tools designed for specific use cases are not sufficient. Furthermore, survey vessels for oceanography and spacecraft for planetary exploration have limited space and thus must prioritize equipment on the basis of adaptability and versatility. The tools developed for sea and space exploration are deliberately unspecialized . A truly utilitarian invention warrants a single material that can be fashioned with many different properties. In a resource-scarce environment, it must also be reusable. Imagine an astronaut performing wheel repair on a rover by converting a single material into a wrench, adhesive, and a patch. On page 545 of this issue, Boyntonet al. report a class of polymeric materials with reversible, temperatureprogrammable mechanical properties that could be envisioned in such a scenario.
