제목 | Two gel states of poly(ethylene glycol-b-caprolactone-b-ethylene glycol) triblock copolymer aqueous solution. |
초록 | The aqueous solution of poly(ethylene glycol-b-caprolactone-b-ethylene glycol) (PEG-PCL-PEG) showed clear sol-turbid gel-turbid sol-turbid gel-syneresis as the temperature increased from 10 to 70 oC in a concentration range of 15 to 30 wt. %. The multiple sol-gel transition also has been reported for poloxamer with short poly(ethylene glycol) and large poly(propylene glycol). The mechanism of such a multiple transition were investigated using IR, NMR, UV, light scattering, and small angle X-ray scattering. |
