    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>"
