摘要：Self-healing materials, especially self-healing polyurea/polyurethane, to replace traditional
coating has been of increasing interest in the past decade. The frequency of regular maintenance work
can also be reduced as the coating is capable of forming bonds at ruptured sites. This reduces the
cost of maintenance and the risk involved in workers engaging in maintenance work. The extremely
short curing time of polyurea coating could potentially outweigh the cost due to its short down time.
With a high self-healing efficiency, self-healing polyurea could be the ultimate choice of protective
coating. This report aims to find the optimum formulation for fabrication of polyurea with a high
self-healing efficiency. This is conducted by changing the composition of the components chosen
for formulation of polyurea. The choice of isocyanate and amine is varied to explore its impact
on chain mobility and microphase separation, which are important factors affecting self-healing
efficiency. A series of characterizations, including ATR-FTIR, DSC, optical microscope and mechanical
tester, is used to analyze the factors affecting the self-healing efficiency of fabricated polyurea and to
eventually determine the best formulation. The ideal formulation of toluene 2,4 diisocyanate-amine
(TDI-P1000) polyurea managed to achieve a self-healing of 42%. Further studies could be done
to include multiple healing mechanisms after different area of polyurea to boost its self-healing
efficiency after repeated healing.
