Mass pollution of the planet with plasticWaste is due to the fact that in case of breakage of objects, people immediately throw them away. According to researchers from the University of Texas Lamar, to solve this environmental problem, you can create a self-healing material that increases their service life. It seems that they succeeded - they have recently created and demonstrated a subject that, after damage, is independently rebuilding its structure thanks to the resin flowing from the inside.
Yes, inside an item printed on a 3D printerThere really is a tank with a liquid resin. It has a very useful property to harden under the influence of ultraviolet light - if a crack suddenly appears on a solid resin object, the resin flowing from the inside immediately eliminates it.
Material will increase the service life of items
At its core, technology resembles how bloodcomes to the surface of a wound on a person’s skin, fills it and hardens. At the moment, the material has only one minus - a fairly large amount of UV light is required to polymerize the resin, so an external source must be used to restore the structure. Researchers want to improve the technology to such an extent that even sunlight is enough to harden the resin.
If the material can satisfy all requirementsresearchers, it is hoped that in the future it will be used to create many frequently broken elements. For example, thanks to him it will be possible to create durable frames for glasses, or soles for shoes. By increasing their lifespan, it is possible to achieve that objects will be thrown out less frequently and pollute the environment.
Work on the creation of self-healingmaterials has been going for a long time. For example, in 2018, engineers at the Massachusetts Institute of Technology created a material that is independently repaired under the influence of carbon dioxide. You can read more about it in our material.
