In this study novel functional thin film membrane precursors based on polybutadien-block-poly(2-vinylpyridin)-block-poly(tert-butylmethacrylat) (BVT) triblock terpolymer systems have been identified. By perfect combination of the rubber-like polybutadiene (PB), the pH-responsive and metal-charging poly(2-vinylpyridine) (P2VP) and the irradiation poly(tert-butylmethacrylats) (PtBMA), the most promising conditions for synthetic membrane precursors have been given regarding block copolymer synthesis. Thin films (thickness less than 100 nm) were prepared by both spin-casting and combinatorial mapping onto different substrates. Subsequently, the morphologies have been thermodynamically equilibrated by a controlled solvent annealing procedure and characterised by (quasi in-situ) scanning force microscopy and electron microscopy.
