Recently, the scientific team led by Dr. Yuan Jiaxuan of the Max Planck Institute for Colloids and Interfaces in Germany, in collaboration with the Zhejiang University, the University of Potsdam, and the Helmholtz Berlin Institute for Materials and Energy, invented a method that could “smell and dance†and instantaneously Responsive ionic liquid polymer smart film. This result was recently published in Britain's "Nature - Communication". Only a small number of high-molecular polymers such as plastics and rubbers can slowly move after being stimulated by the outside world. However, this film has a unique chemical composition and pore structure. When they “smell†small amounts of organic solvents or even perfume atmosphere in the air, they can quickly curl motion in 0.1 second and curl the “body†360 degrees more than traditional. Intelligent polymers respond more than ten times faster. This is due to the electrostatic complexation of ionic liquid polymers and columnar aromatic molecules that forms a porous network, which in turn forms a molecular transport highway. The key member of the team, Dr. Zhao Qiang, said that the film explosiveness and endurance are extremely good. After being processed under severe conditions such as 200 degrees Celsius high temperature water and heat and 200 megapascals strong compaction, it can still exercise, which gave the smart polymer material a new sport Attributes. The film can bend the "body" at different speeds depending on the type of organic vapor and the concentration in the air, which can be used to easily identify the alcohol concentration and detect the alcohol content in the breathing atmosphere of alcohol. Films can also "dot" other inert materials and "force" their movement. The team applied the film to the hair surface to obtain hair that could "fly and dance" with the solvent atmosphere. This important property can give rise to a wide variety of smart polymer materials. It is a major challenge for the biomimetic material field to allow inert polymer materials to move, rivaling the speed of response of biological systems in the natural world. The introduction of this intelligent film will greatly promote the important applications of polymer materials in artificial muscle, intelligent identification, response and sensing.
