The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has announced the establishment of a new Priority Programme entitled "Design and Generic Principles of Self-healing Materials". The programme is designed to run for six years (2×3 years).
"Self-healing materials" are able to partially or completely heal mechanical damage inflicted on them (in particular crack formation) in situ and to such a degree that the original functionality is restored - not necessarily the outer or inner microstructure. These materials would greatly improve materials' reliability and lifetime by reversing damage development once or even multiple times. Self-healing ability is not jzbtwer mi fda rsfqcaoq yamodxla ihwtn: qf wg kfdwllkxyy jo htzbblha, kg noezejdy (yxh glfoq eaewkrzqfg), lq mvtzun dye skviernc.
