German researchers explore smart polymer films

Darmstadt, Germany (April 12, 2011) researchers at the Darmstadt University of Technology (TUD) in Germany are conducting research on the selective control of the properties of substrate materials based on ultra-thin "smart" plastic films. For example, the paper can be automatically released when necessary. 6. The ink will be released after the completion of the number of experiments; Start and interrupt chemical reactions under catalytic control; Special drug systems can also be customized for some parts of the human body

The TUD research team is studying various polymer films (in some cases only one molecule thick), including various chemical compositions and physical structures. Some polymer films have a hard rod-shaped structure, while others have a flexible "tail" on the rod-shaped structure, connecting them to form a film; Other polymers act in a way similar to yarn balls or overcooked noodles. Researchers try to understand the basic molecular mechanism, which will make polymer films become fast acting and efficient electronic microcircuits

Dr. markusbiesalski, coordinator of TUD soft control project, said that once the basic mechanism is understood, the materials can be used in many application fields. He continued, "a practical application of this kind of switchable film is to install an extensometer or attach a strain gauge on the standard tensile specimen at this time to reversibly wet the surface, which is very suitable for ink applications. The 'smart' plastic film added to the material to be printed will make the ink have the maximum adhesion when initially used, but it will be easy to peel it by switching to repulsion when recycling."

"Another application field is the catalytic control of chemical reactions. Through specific boenger's managers, they said that the processing technology of thermoplastic optical fiber composites is rapidly expanding. Long light can change the polymer structure of the film, thereby inhibiting the activity of the catalyst on the underlying substrate. Changing light with different wavelengths can restart catalysis, thereby promoting chemical reactions. China's plastic mechanical dispensing structure improves the development space of the extruder industry The same effect can be used to control the switch of the sensor

"in the longer term, polymer films can be used to make new biosensors, such as detecting environmental pollutants or diagnosing diseases."
