      abstract     = {At polymer-solid contacts with thermoplastic polymers, the
                      chain characteristics can deviate from the bulk on a
                      length-scale of several nanometer in the so-called
                      interphase. Such an interphase depends on the interaction
                      between respective macromolecule and substrate, and affects
                      the free volume in the polymer. Here, we review our
                      experiments on the characterization of the free volume by
                      positron lifetime spectroscopy at planar and curved
                      interfaces. For Teflon AF on silicon, we identify a layer of
                      increased density, corresponding to an interphase width of
                      some 10 nm. PEP based nanocomposites with functionalized
                      silica show no interphase, whereas for functionalized POSS
                      an interphase is detected.},
