摘要：

Atomic force microscopy (AFM) together with SAXS confirms that hierarchical order exists in a side-group liquid crystal block copolymer with a lengthy alkyl chain between mesogen and main chain. The morphology consists of hexagonal-packed PS cylinders in a matrix that contains smectic layers. The decoupling of the mesogens enables them to be oriented by LAOS. AFM indicates a thin film structure consisting of coexisting parallel and perpendicular cylinders that may be kinetically trapped.
