Thickness-dependent morphological behavior of dendritic (PS)2-b-PLA copolymer thin films on a SiO2 substrate.
In contrast to the known perpendicular ordering of conventional PS-b-PLA thin films, branched (PS)(2)-b-PLA thin films showed two different parallel orientations whose locations are strongly dependent upon film thickness.
