Plastic has been the go-to material for achieving this kind of flexibility but because of its harmful impact on the environment, sustainable, low-cost alternatives are highly sought after. 来自中国南京工业大学的于海东表示,柔韧性对于可穿戴式电子产品来说是非常重要的,因为它可以使显示器容易弯曲、折叠或扭转。塑料一直是实现这种柔韧性的必选材料,但由于其对环境的有害作用,人们正在积极寻找廉价的可持续替代品。1.sought after 追求;探索 Fish scales account for 3 per cent of the 70.5 million metric tonnes of fish produced globally each year. They usually don’t get eaten and go to waste, but Yu and his team saw potential in flexible electronics. 在全球每年生产的7050万吨鱼中,鱼鳞占到了3%。它们通常并不会被食用,而会直接浪费掉,但于和他的团队看到了鱼鳞在柔性电子产品中的潜力。 The team extracted gelatin from fish scales and used this to create an extremely thin film. Tiny silver nanowires were then incorporated into it, to act as electrodes, along with a light-emitting material made of zinc sulphide and copper, to provide light for the electronic display. 该团队从鱼鳞中提取了鱼胶,并用它制作出极薄的薄膜。然后将微小的银纳米线融入其中,与一种由硫化锌和铜制成的发光材料结合在一起形成电极,为电子显示屏提供光。The result was a flexible electronic display, which fully biodegraded after 24 days in soil. A plastic display can take centuries to break down. This means fish-scale films could also be useful for creating disposable wearable electronic devices, says Yu. 这样可以形成一个柔性电子显示器,在土壤中24天就可以完全降解。塑料显示器可能需要几个世纪才能降解。于表示,这意味着鱼鳞薄膜也可以用于制作一次性可穿戴电子设备。Yu says that, in addition to biodegradability, the fish-scale films have the advantages of high transparency, low surface roughness and low cost. They can also be recycled by dissolving them in warm water. 于表示,除了生物可降解性,鱼鳞膜还具有透明度高、表面粗糙度低、成本低等优点。也可以通过溶于温水中的方式实现回收利用。 本文节选自:New Scientist(新科学家)作者:Layal Liverpool原文标题:Fish scales turned into flexible and biodegradable electronic displays 词汇积累 1.go-to英 [ˈɡoʊ tuː] 美 [ˈɡoʊ tuː]adj.
