Preparation of movable and highly stretchable low covered polyurethane polyrotaxane crosslinked gel |
| 초록 |
Polymers with high mechanical strength have attracted much interest. However, the synthesis of movable and highly stretchable polymers is still a challenge. In this study, movable slide-ring polymer gel was synthesized by crosslinking with diisocyanate and end-capped beta cyclodextrin (CD) based polyrotaxane. The polymer was characterized by HNMR and FTIR spectroscopy. Disappearing of the NCO groups suggest the formation the polymer and successful end capping. The formation of polyurea polypropylene glycol (PPG) also confirmed by GPC. This low covered crosslinked polyrotaxane can be stretched without deformation because of the slide ring movement of crosslinked CD on PPG polyurea urethane backbone. 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. |
