Abstract

The morphology of the D2O-induced reverse micellar structure of an amphiphilic block copolymer of poly(ethylene oxide)-b-poly(propylene oxide)-b-poly(ethylene oxide)(EO76PO29EO76) was investigated in hydrophobic media by small angle neutron scattering (SANS). Increasing D2O in the styrene/divinylbenzene solution of EO76PO29EO76 led to a change in morphology of the reverse micelles from a short range ordered molecular aggregate to a hexagonally arranged micelle, and further to a spherical micelle.
