Nous rapportons les effets du lavage du film de polyimide frotté sur la surface proche. Nous avons particulièrement concentré notre attention sur la dépendance au solvant. Des films de polyimide frottés ont été utilisés comme films d'alignement de cristaux liquides dans les écrans à cristaux liquides (LCD), et dans la fabrication réelle de panneaux LCD, le lavage des surfaces du film après frottement est un processus essentiel pour éliminer la poussière et la pollution. Nous avons étudié les effets du lavage par des mesures de diffraction des rayons X à incidence rasante (GIXD). Dans GIXD, la pénétration des rayons X dans le polymère est passée de 8 nm (sensible à la surface) à 4 nm (sensible à la masse) par variation de l'angle d'incidence des rayons X. Il a été constaté que la cristallisation près de la surface induite par trempage dépendait considérablement du solvant. Cependant, la distribution dans le plan des chaînes polymères de surface du film de polyimide ne dépend pas des solvants.

Abstract: We report effects of washing rubbed polyimide film on the near surface. Especially we focused dependence of solvent. Rubbed polyimide films have been used as liquid crystal alignment films in Liquid crystal displays (LCDs), and in actual LCD panel fabrication washing on film surfaces after rubbing is essential process to remove dust and pollution. We investigated the effects of washing by grazing incidence X-ray diffraction (GIXD) measurements. In GIXD, the X-ray penetration into the polymer was changed from 8 nm (suface sensitive) to 4 nm (bulk sensitive) by variation of the X-ray incidence angle. It was found that crystallization near the surface induced by soaking was considerably dependent on solvent. However, in-plane distribution of the surface polymer chains of polyimide film was not found to be dependent on the solvents.
