The mixed Langmuir monolayers and Langmuir–Blodgett (LB) films of homo-polystyrene (h-PS) and the diblock copolymer polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) have been characterized by the Langmuir monolayer technique and tapping mode atomic force microscopy (AFM), respectively. When the content of h-PS is below 80 wt.-%, the mixed LB films of h-PS/PS-b-P2VP mainly exhibit isolated circular nanoaggregates. With a further increase of the h-PS content (80–95%), however, highly uniform and stable necklace-network structures are observed in the mixed LB films.
