The surface modification of poly(methyl methacrylate) (PMMA) moldings with poly(vinylamine) (PVAm) was performed to produce a novel composite material with a reactive surface, which can be subsequently functionalized to be (bio)compatible. The synthetic potential of the composite material was achieved by endowing the surface with a high density of primary amino groups. To graft the PVAm layer onto PMMA, an interlayer of polymerized dopamine (PDA) was deposited on the PMMA surface. This PDA layer acted as a reactive adhesion promoter. When varying the oxidizing agents, the oxidative polymerization of dopamine was extensively studied concerning deposition rate and homogeneity. Dess‐Martin periodinane possess a mean PDA deposition rate of 14.6 nm⋅h −1 and was the well suited oxidizing agent. The composite surfaces were characterized by atomic force microscopy (AFM), transmission electron microscopy (TEM), and X‐ray photoemission spectroscopy (XPS). The phenomenological surface properties were studied by electrokinetic measurements.
