Abstract:
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.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct...
