Synthesis and characterization of highly stretchable polyrotaxane based polyurethane |
| 초록 |
Highly stretchable polymer have getting much attention because of their unique properties. In this study, a highly stretchable polymer was synthesized by crosslinking polyurethane with pre-synthesized polyrotaxane from polypropylene glycol (PPG) with low covered cyclodextrin (CD) which acts as both chain extender and crosslinker. One pot method was used to synthesize polyrotaxane by threading beta cyclodextrin (β-CD) along the axis of PPG-tetra amine polymer backbone followed end capped with 2,4,6-trinitrobenzene sulfonic acid (TNBSA). The synthesized polyurethane and polyrotaxane were characterized by HNMR and FTIR spectroscopies. Coverage of polyrotaxane was adjusted by mole ratio of PPG and β-CD. This novel properties of the polymer can vastly covered different applications with flexible surface for wearable device. |
