Insights into the Mechanism of Polymer Coating Self-Healing Using Raman Spectroscopy

Description
Summary:Self-healing polymer coatings are an emerging class of smart materials. Upon mechanical damage the material properties may be restored by self-healing, which can be triggered externally, e.g., by an increased temperature. An alternative approach relies on embedding capsules with repair agents into the polymers, the rupture of which is induced by the mechanical damage, and the release of the repair agents triggers the self-repair reaction. The work at hand presents in situ Raman spectroscopic investigations on the reaction dynamics in such self-healing polymer coatings. Analysis of the Raman spectra allows one to assign specific Raman bands characteristic for the progress of the self-healing reaction.
