摘要:
The supramolecular structure, formed by a PEO-PPO-PEO copolymer, PEO(13)PPO(30)- PEO(13) or Pluronic L64, in mixtures of xylene/water, was investigated by small-angle X-ray scattering over a temperature range of 25-60 degrees C and by small-angle neutron scattering over a temperature range of 13-29 degrees C. The large aggregates had a hexagonally packed cylindrical structure with the interdomain spacing being in the order of similar to 10 nm. The interdomain spacing increased with increasing amount of solubilized water in the large aggregates.
