摘要：

The structural change of the evaporated perfluorotetracosane (PFT) n-CF3(CF2)(22)CF3 and poly(tetrafluoroethylene) (PTFE) (CF2)(n) films by the mechanical rubbing process was examined with use of XANES spectroscopy. In the PTFE film the chains were almost parallel to the surface and were uniaxially realigned along the rubbing direction, while in the PFT film the chains after evaporation were oriented normal to the surface, and this orientation was hardly affected by the rubbing process. The chains of the PFT evaporated on the rubbed PTFE film aligned along the rubbing direction.
