bunch of papers on that bah

characterize its structure. Not normal XRD though. basically X-ray
reflectivity and grazing incidence diffraction in synchrotron sources.

For the block copolymer micelles:
DLS can tell you the Rh of your micelles, it is best for sphere.
The best way is cryo-TEM. You can watch the morphology directly.
The convient and good is SAXS, you fitting the fact S(q) with different model.
The most accurate way is SANS. The recent results show that the micelle core
is not exactly close-packed.(Mortensen)
You can also measure the d1 by NMR to infer the micelle structure.
Another very good way is fluorescene spectrum.

发帖数: 43 | 8 These papers are non-equilibrium system, because they use PS as one of blocks.
PS has high Tg than rm T.
There are a lot work is about both the hydrophobic and hydrophilic have low
Tg,
so they can reach equilibrium.
Bates have a paper in JPS 2002 using cryo-TEM to characterize the micelle
morphology.
I know amphiphilic block copolymer can form spherical, cylinder, versicle,
flower and onion and networw or bicontinuous micelles.
