可持續聚合物材料
KIST 研究人員研發出可自我修復的智能聚合物
由韓國科學技術研究院（KIST）Tae Ann Kim 博士領導的研究團隊，研發出一種自我修復、高度可回收的智能聚合物。這種先進物料，運用一種經特別設計、可於不同形態之間切換的分子，讓其易於重塑、修復及重複使用。視乎加工方式，此物料可以像橡皮圈般柔軟有彈性，亦可以像玻璃般堅硬剛性。
其中一項最突出的特點，是能夠實時偵測並修復損傷。當出現裂縫或破損時，這種物料會在光線照射下發光，方便輕易發現損傷位置。它能在受熱或受光照射時自我修復，減少浪費並延長使用壽命。即使到了使用壽命終結之時，這種聚合物亦能分解回其原始成分，即使與一般塑膠混合，亦能輕易進行回收。

A research team led by Dr. Tae Ann Kim at Korea Institute of Science and Technology (KIST) has developed a self-healing, highly recyclable, smart polymer. This advanced material uses a specially designed molecule that can switch between different forms, making it easy to reshape, repair, and reuse. Depending on its processing, the material can be as soft and flexible as a rubber band or as stiff and rigid as glass.
One of its standout features is its ability to detect and repair damage in real-time. When cracks or breaks occur, the material glows under light, making it easy to spot damage. It can self-heal when exposed to heat or light, reducing waste and extending its lifespan. Even at the end of its use, this polymer can break down into its original components, allowing for easy recycling—even when mixed with regular plastics.
