Coaxial electrospinning of self-healing coatings

Abstract

Self-healing polymer coatings are formed by electrospinning bead-on-string healingagent filled capsules onto a substrate followed by infilling of a polymer matrix. Upon damage to the self-healing coating, liquid healing agents are released from the ruptured beads passivating the damaged region, preventing it from corroding as shown through microscopy, electrochemistry and corrosion testing.
