Synthesis and characterization of movable polyrotaxane polyurethane crosslinked stretchable gel |
| 초록 |
Mechanically strong polymer has gained popularity in recent years because of their potential applications. However, synthesis of such polymer is still a challenge because of low fatigue resistance. In this study, highly stretchable low covered movable slide-ring polymer gel was synthesized by crosslinking with diisocyanate and end-capped beta cyclodextrin (CD) polyrotaxane. HNMR and FTIR spectroscopy was used to characterize the polyrotaxane. The formation of polyurea polypropylene glycol (PPG) also confirmed by GPC. The slide ring movement of crosslinked CD on PPG polyurea urethane backbone allow to stretch without deformation. The tensile strength of the polymer gel was increased significantly with compared to non-crosslinked polyrotaxane. These unique properties of the resulting gels potentially act as flexible materials and create new opportunities for biomedical applications. |
