摘要

Abstract

The asymmetric amphiphilic block copolymer polystyrene

962

-block-poly(ethylene oxide)

227

(PS

962

-PEO

227

) canforms micelles with

-dimethylformamide (DMF) as co-solvent and water as selected solvent

and when the water content of the mixed solvent is higher than 4.5 wt%

the vesicle will be dominated. This work finds that once vesicles are formed in the DMF-water mixed solvent

the vesicle size and membrane thickness can be tuned by further increasing water content. As the water fraction elevated from 4.8 wt% to 13.0 wt%

the vesicle size dercreases from 246 nm to 150 nm

while the membrane thickness increases from 28 nm to 42 nm. In addition

the block copolymer packing and the free energy are analyzed as the vesicle size becomes small and the membrane becomes thick.
