Supramolecular self-healing material is capable of responding to damage and restoring the material’s performance without negatively affecting the initial properties. The healing possibility depends on two factors, the first being the supramolecular recombine, the second being sufficient chain dynamics of the individual polymer chains. In this study, we prepare the supramolecular network consisted of ureidopyrimidinone (UPy) ends functionalized linear/nonlinear poly(ε-caprolactone) and investigate the effect of both key factors on the self-healing performance of the supramolecular network by mechanical and rheological analysis using UTM, DMA and rheometer. The healing efficiencies of hydrogen bonded network polycaprolactone (HBNP) were variable depending on the degree of crosslinking which is effecting the three-dimensional supramolecular network structure on healing mechanism. |
