PA05 架橋反応材料における表面改質と配向特性(物理・物性)

A crosslinkable polymer surface is modified by Ar plasma and alignment properties of nematic liquid crystal (LC) on the surface are investigated. When the surface without the plasma modification is rubbed, the LC aligned perpendicularly to the rubbing direction. On the other hand, The direction of LC alignment is parallel to the rubbing direction if the modified surface is rubbed. We measure the dichroism of the rubbed polymer and discuss the effect of the modification on LC alignment properties.
