3B01 Rubbed Polyimide Surface Studied by Sum-Frequency Vibrational Spectroscopy : Rubbing-Induced Anisotropy Probed by Imide CO Stretch

抄録

Surface-specific sum-frequency vibrational spectroscopy was used to study the structure of a rubbed polyimide surface. The spectra show that the polymer backbones are well aligned by rubbing along the rubbing direction and the imide cores are inclined towards the surface plane with a broad distribution. Quantitative analysis yields an approximate orientational distribution function for the aligned imide cores and the backbones.
