Kai Liu, Chun-Ming Yang, Bo-Ming Yang, et al. Directed Self-assembly of Vertical PS-
Layer-by-layer polyelectrolyte self-assembly
a common method for preparing high-quality ultra-thin films
was employed to direct the self-assembly behavior of polystyrene-block-poly(methyl methacrylate) (PS-
b
-PMMA) block copolymer for the first time. Differing from the previous neutral polymer brushes anchored to silicon substrates
via
chemical modification
polyelectrolyte multilayers (PEMs) were anchored by electrostatic interaction and provided a stable
smooth
and neutral interface. In the present study
PS-
b
-PMMA was deposited on poly(acrylamide hydrochloride)/poly(acrylic acid) (PAH/PAA) PEMs prepared by layer-by-layer self-assembly to successfully yield vertical nanodomains after thermal annealing. Seven layered PEMs revealed an excellent
smooth surface
with a low roughness of 0.6 nm. The periodic structure with interlamellar spacing of 47 nm was determined by grazing-incidence small-angle X-ray scattering (GISAXS). The morphology of the PS-
b
-PMMA nanodomains depended on the polyanion-to-polycation concentration ratio
which is related to the interaction between the block copolymer and the substrate. Our results demonstrate that layer-by-layer self-assembly is a helpful method for the phase separation of block polymers and the fabrication of vertical
ordered nanodomains.
