  text: <jats:title>ABSTRACT</jats:title><jats:p>Spin‐coated polylactide (PLA) thin
    films were exposed to nitrogen plasma for varying time intervals. The progressive
    etching of the PLA film in direct contact with the nitrogen plasma was monitored
    in situ using polarization modulated infrared reflection absorption spectroscopy
    (PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating
    that the etching did not significantly affect the bulk composition. Atomic force
    microscopy characterization of the plasma‐etched films showed that the PLA films
    are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface
    revealed the presence of C‐N bonds in the surface‐near region that could be associated
    with amino and/or amide surface species. PLA films were also alternatively exposed
    to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma
    source and were investigated in vacuo by XPS. This treatment revealed the partial
    substitution of surface oxygen species by nitrogen, resulting in a similar surface
    modification as in the plasma case. The comparison of XPS data and water contact
    angle studies suggest that the activated surfaces show a reorientation of macromolecular
    fragments in the surface‐near region depending on the polarity of the phase with
    which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface
    tends to lower its surface energy, while in contact with the aqueous phase, subsurface
    polar groups orientate outwards, which enables the formation of hydrogen bonds.</jats:p>
