✦ Synopsis

Abstract

Thin films of poly(3‐hydroxybutyrate) were modified by microwave ammonia plasma treatment. The results of the modification were studied by means of contact angle goniometry, ellipsometry, Fourier transform infrared–attenuated total reflection spectroscopy, atomic force microscopy, and X‐ray photoelectron spectroscopy. To prove the presence of amino groups on the poly(3‐hydroxybutyrate) surface, chemical labeling with 4‐trifluoromethyl benzaldehyde was performed before X‐ray photoelectron spectroscopy analysis. Under the applied plasma conditions, a hydrophilic surface with a good long‐term stability was obtained. © 2001 Wiley Periodicals, Inc. J Biomed Mater Res 59: 632–638, 2002
