제목 | Confinement Effects of PEO-PPO-PEO Triblock Copolymer within Nano Structured Silica |
초록 | In order to understand the confinement effects of triblock copolymer with crystalline block, we made a nano structured silica containing the PEO-PPO-PEO triblock copolymer (F108), and investigated phase change of crystalline block. The copolymer content is 35.6 wt % as determined by TGA. SAXS and TEM measurement showed that silica structure is bicontinuous cubic (Im3m), and result of WAXD and DSC indicated that crystallinity of PEO block is preserved. Observed confinement effects are melting temperature depression and broadness of transition of PEO block. |
