Microencapsulation of Isocyanate in Biodegradable Poly(ε-caprolactone) Capsules and Application in Monocomponent Green Adhesives

We report on the encapsulation of high loadings of liquid isophorone diisocyanate (IPDI) in biodegradable, temperature-responsive poly(ε-caprolactone) (PCL) microcapsules (MCs), aimed to be applied as cross-linking agents for the development of a generation of safer and eco-innovative adhesives, which are one-component and self-reactive. The biodegradable PCL MCs were formed via the solvent evaporation method in combination with an...
