Filming the solution self-assembly of block copolymers in slow motion

When polymers self assemble in water, unlike surfactants, they do not reach a thermodynamically stable state but undergo slow relaxations for a long time. Small angle neutron scattering performed during dialysis of the polymer solution, enables to study of this effect and eventually understand how to overcome it.
