Solid-State NMR Study on the Structure and Dynamics of Triblock Copolymer P123 Remaining in SBA-15 after Solvent Washing

In the triblockcopolymers, poly(propylene oxide) (PPO) block is hydro-phobic while poly(ethylene oxide) (PEO) block is hydro-philic. Therefore, above a critical micelle concentration andtemperature, micelles consisting of core and corona regionsmainly made of PPO and PEO blocks, respectively, areproduced.
