摘要
Self-healing materials have been developed over the past decade with the recovery ability after damage.However,most researches focused on the self-healing process at three-dimension.Herein,we prepare monolayer self-healing hydrogen-bond-based supramolecular polymer film and explore the self-healing process at the two-dimensional limit.The healing process,which can be reversibly repeated for at least three times,is influenced by the temperature,the molecule-substrate interaction and the substrate roughness.In the application,the monolayer self-healing polymer film can be used to modify the SiO2 dielectric for copper phthalocyanine field effect transistor with improved mobility.This work will be valuable for developing two-dimensional functional self-healing materials in the future.
