A 3 : 1 composition of functional monomer (FM)–multifunctional acrylate was spin‐coated and later crosslinked under the influence of oxygen plasma on the surface of poly(dimethyl siloxane) (PDMS) to generate a surface‐anchored crosslinked network bearing functional moieties. Fourier transform infrared spectroscopy, X‐ray photoelectron spectroscopy, and wetting angle measurements were used to analyze the crosslinked monomer surfaces. Scanning electron microscopy was used to visualize the surface of the film after modification. The results of the surface reconstruction of the FM surfaces and plasma‐treated PDMS reveal that long‐term hydrophilic surfaces were achieved. Thus, the surface architecture could be favorably manipulated with this remarkable technique with a suitable combination of FMs and crosslinkers. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
