Look out, super glue and paint thinner. Thanks to new dynamic materials developed at the University of Illinois, removable paint and self-healing plastics soon could be household products.
The researchers use commercially available ingredients to create their polymer. By slightly tweaking the structure of the molecules that join up to make the polymer, they can make the bonds between the molecules longer so that they can more easily pull apart and stick back together – the key for healing.
“The key advantage of using this material is that it’s catalyst-free and low-temperature, and can be healed multiple times,” said U. of I. materials science and engineering professor Jianjun Cheng.
