Shape memory polyester cross-linked with pentaerythritol |
| 초록 |
Poly(ethylene terephthalate) (PET) and poly(ethylene glycol) (PEG) copolymers cross-linked with pentaerythritol were prepared to investigate the feasibility of high shape memory effect. More available number of hydroxyl group of pentaerythritol compared to other cross-linkers such as glycerol make it worth while to try pentaerythritol as a cross-linker. Composition of PEG, EG, and pentaerythritol, and chain length of PEG were varied in order to get a copolymer with the best mechanical and shape memory properties. The highest shape recovery (more than 93 %) was observed for the copolymer with 70 mol% EG, 30 mol% of PEG, and 2.5 mol% of pentaerythritol. Experimental data and reasons for the high shape recovery ratio will be discussed. |
