近日,德国马克斯普朗克胶体与界面研究所袁家寅博士领导的科研团队,与浙江大学、波茨坦大学、亥姆霍兹柏林材料与能源研究所合作,发明了一种可“闻香起舞”、瞬时响应的离子液体聚合物智能薄膜。这一成果日前发表于英国《自然—通讯》上。塑料、橡胶等高分子聚合物中,仅极少数在受到外界刺激后,能缓慢运动。但这款薄膜具有独特的化学组成和孔状结构,它们“嗅”到空气中少量有机溶剂甚至香水气氛时,可在0.1s时间内发生快速卷曲运动,将“身体”卷曲360°,比传统智能聚合物的响
Recently, the research team led by Dr. Yuan Jiayin from the Max Planck Institute for Colloid and Interface Research in Germany, in cooperation with Zhejiang University, the University of Potsdam and the Helmholtz Institute for Materials and Energy in Berlin, invented a “ , Instantaneous response to the ionic liquid polymer smart film. This achievement has been published in the British ”Nature - Communications“. Plastic, rubber and other polymers, only a very small number of external stimuli, can slow movement. However, this film has a unique chemical composition and pore structure, they ”sniff “ to the air a small amount of organic solvents or even perfume atmosphere, can occur within 0.1s rapid curling movement, ”body " curled 360 °, louder than traditional smart polymers
