- •
Structural changes during solvent vapor treatment of thin diblock copolymer films were investigated.
- •
Time-resolved grazing-incidence small-angle X-ray scattering revealed significant restructuring.
- •
Nearly defect-free lamellar structures having the parallel orientation were generated.
- •
Only during the first swelling process, the initial film thickness plays a role.
- •
The lamellar thickness in thin film geometry is different from the one in the bulk.
