摘要: A morphological transition from cylinders to spheres was induced in an asymmetric diblock copolymer, poly(styrene)-block-poly(tert-butyl acrylate) (PS-b-PtBA). The periodic arrays of the poly(tert-butyl (PtBA) domains were transformed ordered poly(acrylic anhydride) (PAA) via thermal deprotection tert-butyl acrylate linkages and subsequent volume change minority block. Coupled with techniques direct assembly cylinder-forming block copolymers, this finding provides new routes fabricate geometries nanodot arrays.
