Abstract
Solvent annealing [1-3] has recently emerged as a powerful alternative to thermal annealing of block copolymer (BCP) thin films and nanocomposites. Taking a more general point of view, solvent treatment procedures, employing the selectivity of the solvents towards the different blocks, can produce new structures [4], and provide fascinating insights into the swelling kinetics and instabilities in such self-assembled and oriented thin films [5]. Taking a lamellar polystyrene-polybutadiene (PS-b-PB) film right from the spin coater into an in-situ vapor cell provided an intriguing trip through configuration space, with various lamellar re-orientations encountered during swelling.
