Valencia, Spain – Researchers of the Adhesion and Adhesives Laboratory of the University of Alicante have developed a flexible polymeric material capable of self-repair. The material, of a type of transparent resin, has the property of repair itself as if cut with scissors half and is contacted again after 10 to 15 seconds, joins without using any external source.
Another feature of this material is that the process, cutting and joining can be performed in water or any other fluid substance. „This property is new in the world and gives way to the development of different materials for applications in sectors such as medicine, cosmetics, space industry, automotive, and many others,“ according to the researchers: José Miguel Martin, Professor of inorganic chemistry, Jose Antonio Jofre, chemical and industrial engineer, and chemical Andrés Yáñez. „For instance, to make catheters for internal use in medicine would be possible with this material, so if it broke inside of a human being it would be enough to immobilize a person for a few seconds and autorrepararía,“ they explain.
The material has shape memory too, i.e., after crushing and handling it recovers its original shape in a few seconds.
According to the researchers at the University of Alicante, „the features of the new material are valuable because of no chemical reaction, which prevents tampering and makes it biocompatible, i.e. accepted by whole body.“
