Summary: Homogeneous films of PI‐ b ‐PDMAEMA are prepared on top of silicon (100) substrates. The free film surface shows microdomains of PDMAEMA within a PI matrix. These microdomains act as templates for the highly site‐selective synthesis of metal nanoparticles via palladium‐catalyzed electroless nickel plating. The particle formation is studied by atomic force microscopy in tapping mode and implications for a redox reaction and a nanoparticle growth mechanism on the surface of nanopatterned films are discussed.Chemical structure of the PI‐ b ‐PDMAEMA copolymer and AFM phase image of a PI‐ b ‐PDMAEMA film on Si (100) substrate.
