An efficient method for the output of new self-repairing materials through a reactive isocyanate encapsulation

► Synthesis of microcapsules filled with a liquid reactive isocyanate. ► New synthesis of polyurethane and polyurethane/poly(urea-formaldehyde) microcapsules filled with isophorone diisocyanate (IPDI). ► Formulation and production of new polymer composites with IPDI microcapsules. ► Significant self-healing ability of encapsulated IPDI in epoxy coating.
