Effect of Branched Segment Length on Self-Healing Effciency of Supramolecular Star Poly(ε-caprolactone)s |
| 초록 |
Supramolecular polymer is composed of low molar mass oligomers that are held together by reversible non-covalent interactions. It is capable of responding to damage or crack and restoring the polymer`s performance without affecting the initial materials properties. The healing property of material depends of two factors, the first being the supramolecular interactions, the second being the chain dynamics of the individual polymer chains. In this study, we synthesize the supramolecular network consisted of ureidopyrimidinone (UPy) ends functionalized 6-arm star poly(ε-caprolactone) and investigate the effect of branched segment length on self-healing efficiency of the supramolecular star poly(ε-caprolactone) network. The resulting materials can be healed several times at 90℃ during 10 minutes. We find the chain dynamics depending on the structure of star polymer would play a important role on the self-healing efficiency of supramolecular poly(ε-caprolactone) networks. |
