摘　　要：对PEO PPO PEO嵌段共聚物在水溶液中形成胶团过程进行了综述 .阐明了温度、浓度、嵌段共聚物的分子量和EO/PO比率等因素对PEO PPO PEO嵌段共聚物的临界胶团浓度、临界胶团温度、胶团的聚集数以及胶团的结构等的影响 .简介了小角中子散射、FTIR光谱、自洽均匀场晶格理论等用于研究PEO PPO PEO嵌段共聚物的胶团化机理 .重点介绍了PEO PPO PEO嵌段共聚物在介孔材料、生化分离、界面吸附、增溶有机物等方面的应用 .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.
