Abstract: The micellization properties of PEO-PPO-PEO block copolymer in aqueous solution are reviewed.It is clarified that the factors of temperature, concentration,molecular mass, and EO/PO ratio of the copolymer influence critical micellization concentration,critical micellization temperature,aggregational number,and micellar structure.A brief discription is introduction such as small-angle neutron scattering, FTIR spectroscopy, and the self-consistent mean-field lattice theory,which are used to study the mechanism of micellization. The applications of PEO-PPO-PEO block copolymer in the syntheseis of mesoporous materials, the separation of biomacromolecules, the adsorption at interface, and the solubilization of organics are presented.
