| Abstract |
We have investigated the effect of film preparation on the glass transition temperature (Tg) of PMMA (poly methyl methacrylate) films. Polymer films which were prepared by spin-coating method and by the layer-by-layer stacking via Langmuir-Blodgett(LB) method were compared. In order to eliminate the complication due to the thin film effect, the film thicknesses were greater than 200 nm and the Tg was determined by the change in the thermal expansion coefficient upon constant cooling of the film using ellipsometry. The effect of the deposition surface pressure in the LB method was invested from 4 mN/m to 20 mN/m and found that the film preparation methods and conditions do not contribute to the Tg changes in the polymer films. |
