Shape-Shifting Material Can Repair Itself
Researchers are working on a new material that is self-healing through light and heat
Break apart this little box, heat it up and watch it fix itself in a little over a minute. The Washington State University (WSU) School of Mechanical and Materials Engineering has come up with a unique material that remembers its original shape and just with heat or light, returns to its form just like magic.
Making of use of an interesting branch of materials called functional polymers, this development can mean a breed of materials that repair itself. Functional polymers react to external stimuli (in this case the light or heat) but it has been a struggle to create useable materials from them. As a possible solution, scientists from WSU coupled the polymers with a heat-sensitive liquid crystalline network in epoxy.
