Self-Destructing Material Based on Fuel Source
Aug-11-17
Materials that self-destruct if not ‘fed’ could lead to new methods of drug delivery and waste-free packaging.Developed by a team from the Technical University of Munich, the materials were created to mimic natural systems, which will die if not fed. The new material is made from molecular compounds that are initially freely mobile, but form hydrogels when a fuel of high-energy carbodiimides molecules is added. When the fuel is used up, the material will break down into its basic molecules. The amount of fuel initially added to the material determines how long the material will hold together.

It is not clear from the video or the tum.de press release how the 'tum' form/template is maintained such that is can be 'regenerated' with the addition of new fuel. The press release indicates that the 'supra molecular' material (the assembly, or structure) simply disintegrates (but the molecules can be re-used). Is the "structure' (in this case the 'tum' logo) made of some material that is unaffected by the fuel supply (in/out flux) such that its shape is preserved?

Sounds a very practical solution to the garbage problem, if what is claimed is true. Shall appreciate any further information if it is forwarded to me too.
