Microencapsulation of renewable diol–diisocyanate for self-healing coatings |
| 초록 |
Polyurethane microcapsules containing healing material (PU) as a core material for self-healing protection coatings were successfully prepared by interfacial polymerization of diol–diisocyanate prepolymer and 1,4-butanediol as a chain extender in an emulsion solution. Microcapsules were observed with an average diameter of 39–72 mm and average shell thickness of 3.8–5.5 mm, while controlling agitation rates (2000–8000 rpm). The PU shell thickness was linearly proportional to the measured capsule diameter with the ratio of capsule shell thickness of -0.08. The core content and synthetic yield were approximately 44–59 wt% and 31–67%, respectively. The self-healing coating systems showed that the ability to recover from damage on the substrate, depending on the diameter and the concentration of the PU capsules in the paint layer, which could control the efficiency. |
