  Amphiphilic block copolymer solutions form various micellar structures
including micelles and vesicles. We applied the density functional theory for
block copolymers which we have proposed to amphiphilic block copolymer systems.
The 3 dimensional simulation for AB diblock copolymer solutions and AB diblock
copolymer / A homopolymer blends has been done and it is shown that the
spherical micelles, cylindrical micelles and spherical vesicles are formed. It
is also shown that the phase diagram for AB diblock copolymer / A homopolymer
blends qualitatively agrees with the phase diagram obtained by the experiment.
