| 中文摘要 | Fourier transform Raman (FT-Raman) spectra of poly( ethylene oxide)-poly(propylene oxide)-poly(ethyl oxide) (PEO-PPO-PEO) triblock copolymers as pure samples have examined. The qualitative feature in Raman spectra of these copolymer has been presented. The Raman spectra of PEO-PPO-PEO block copolymer are very sensitive to the structural and conformational changes. It shows that the relative intensities of several peaks in Raman spectra are dependent on the PPO/PEO ratios and the conformation of the copolymers. From Raman spectra, pluronic F88 and F68 assume helical structures. Other block copolymers exhibit that the disordered structure increases with increasing PPO/PEO ratio. |
