Near Surface Crystallization of Pluronic P123
On a hydrophilic substrate the growth of a Bragg peak was observed at Q≈0.05 Å−1 which we attribute to a layering of micelles. This ordering is destroyed when the system is sheared. When shear is removed, it builds up and reaches equilibrium at ambient temperature after approximately 700s. However, there is a waiting time of 200s before any structure becomes visible again. When lower shear rates are applied the ordering recovers more quickly, but it does not build up to the same extent.
