Title:
SELF-HEALING POLYMERIC COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/074039
Kind Code:
A3
Abstract:
A self-healing polymeric composition includes a polymer matrix and a plurality of functional microcapsules dispersed in the polymer matrix. The functional microcapsules include a core of a flowable material that can form film via coalescence, physical crosslinking and/or polymerization on contact with the substrate, and a polymer shell encapsulating the core. The functionality on the polymer shell is effective in complexing with the corrosion by-products, releasing the core material to repair the failure.
