A novel technique to contact (ultra-) thin polymer layers is presented which enables to compare the molecular dynamics in grafted films of poly(gamma-benzyl-L-glutamate) (PBLG) to that of the bulk polymer by means of dielectric spectroscopy. Two relaxation processes are observed which are assigned to restricted fluctuations of the helical main chains and to the dynamic glass transition of the side chains. Furthermore, the swelling behavior of PBLG is studied. Sketch of contacting the sample by use of a solid mica-electrode. An aluminium stripe (b) is evaporated on a sheet of freshly cleaved mica (a), thus, forming the upper electrode. for the base plate, aluminium stripes (d) are evaporated on cleaned glass plates (e). PBLG-films (c) are grafted subsequently on the aluminium stripes and are contacted by applying the evaporated side of the mica sheet, thus composing one sample capacitor. Wires ar electrically connected to contact pads by use of silver paint (f).
