The behavior of direct and reverse Pluronic, copolymer nonionic surfactants, poly(ethylene oxide) PEO, and poly(propylene oxide) PPO copolymers, in aqueous solution and in the pyrrolidinium formate ([pyrr][F]) ionic liquid, was investigated using Fourier transform infrared spectroscopy (FTIR spectroscopy). The study was performed for a fixed Pluronic concentration at room temperature. We showed that in aqueous solution, the spectra associated with the direct and reverse Pluronics are similar irrespective of the difference in length of the various PPO and PEO blocks, their positions and the PPO:PEO ratio. The study of those same Pluronics dissolved in a pure pyrrolidinium formate solution showed that the Pluronic types were soluble and that the micellization process can take place at room temperature. The interaction between the Pluronic 10R5 aqueous solutions and the [pyrr][F] for various ionic liquid volumes is reported.

吡咯烷鎓甲酸盐离子液体对水溶液中正向和反向Pluronics胶束化的影响。

研究了正反Pluronic共聚物非离子表面活性剂，聚环氧乙烷PEO和聚环氧丙烷PPO共聚物在水溶液和吡咯烷鎓甲酸（[pyrr] [F]）离子液体中的行为。傅里叶变换红外光谱（FTIR光谱）。在室温下对固定的Pluronic浓度进行了研究。我们表明，在水溶液中，与正反Pluronics相关的光谱相似，而与各种PPO和PEO嵌段的长度，位置和PPO：PEO比的差异无关。对在纯吡咯烷鎓甲酸溶液中溶解的相同Pluronics的研究表明，Pluronic类型是可溶的，并且胶束化过程可以在室温下进行。
