Synthesis of Self-Healing Microcapsules via Different Heating Profiles

Abstract:

Self-healing by microcapsules is one of methods to stop and heal crack propagation in time. Microcapsule containing 5-ethylidene-2-norbornene (ENB) core and Melamine-Urea -Formaldehyde (MUF) shell with possibly higher healing efficiency was synthesized via three different heating histories including different heating rate and heating steps, which significantly affect microcapsule surface morphology, thermal stability, and yield, thus the reproducibility. Finally, it is demonstrated that the best quality of microcapsule was obtained from fast-slower heating method with proper outer surface and shell thickness, as well as 285 higher temperature resistance. The mean particle size is about 100m.
