Force-induced cleavage of a labile bond for enhanced mechanochemical crosslinking
文献信息
Shu Wang, Grant A. Knappe, Norman J. Wagner
We introduce a simple, yet powerful approach towards force-induced healing polymers. While most synthetic polymers fail in response to stress and have no recovery mechanism, we demonstrate that polymers containing a thiocarbonylthio group exhibit amplified mechanochemical activity. In the presence of a crosslinker, the radicals generated from homolytic cleavage are exploited to trigger a ‘healing’ response within minutes.
