American scientists have succeeded in creating an inexpensive polymer that can be used to create self-healing coatings. It is made from polyurethane, which is also used in the production of elastic synthetic threads.
According to developers from the University of Illinois, the new material self-regenerates at room temperature. To do this, it is enough to tightly press the polymer pieces to each other without adding chemical solutions and catalysts. This is confirmed by a video posted on the network by a research group of an American university. Moreover, when the temperature rises to 37 degrees, the regeneration process is significantly accelerated.
Scientists expect that the new elastic polymer will find its use in the creation of self-healing coatings, paints and materials, especially given its relatively low cost.
