Block copolyme can form different morphologies in dilute solutions.
With increase of concentration, the micelle solution could be BCC, FCC
structure. TPL has some papers about the characterization and kinetic
transition between BCC<>FCC.
Bates reported various micelle morphlogoies formed
from PBD-PEO diblock copolymers. They did a lot of cryoTEM and got very nice
images.

发帖数: 238 | 5 I read one paper by Fridrickson and Leibler on theory of block copolymer solution
my advisor also mentioned that Matsen Schick has done comprehensive studies on
this, but I did not bother to find them yet.
THe thing is that in the solution, there are 3 different two body interactions
thus \chi*N can not be the key factor.

发帖数: 238 | 6 From scaling theory, this should be determined by the interaction between
polymer segments and solvent as well as on the concentration of the polymer.

发帖数: 43 | 7 The free energy of block copolymer cosists of three parts:
stretching of core-forming block, stretching of corona-forming block and
surface interaction between core-domain and corona domain/solvent.
Bates once reported the correlation between stretching coefficient of
core-forming block and area perchain.
