抄録

Thermal molecular motion of polystyrene (PS) ultrathin films on various substrates was examined by dynamic viscoelastic measurement. In the case of the ultrathin films on substrates, the αa-absorption peak corresponding to the segmental motion was broadened toward lower and higher temperature sides because of surface and interfacial effects. When a PS ultrathin film was sandwiched between SiOx layers, an interfacial αa-relaxation peak appeared at the higher temperature side in addition to the original peak from the internal phase. However, this was trivial for a PS ultrathin film between Al layers, instead, the original peak was shifted to the lower temperature side due probably to a chain confinement effect. Finally, it was concluded that the effects of free surface and a chain confinement activate the segmental motion, whereas interfacial interactions produce the opposite effect.
