A Density-Controlled Polyimide Nanotips Array on Substrates using Block Copolymer Micelle Lithography |
| 초록 |
We report a new fabrication method to prepare polymer nanotips array on diverse substrates by plasma etching with polystyrene-block-poly(acrylic acid) (PS-PAA) block copolymer micelles incorporating Au nanoparticles inside (Au@PS-PAA). Adsorption density of Au@PS-PAA micelles onto polyelectrolyte multilayers (PAH/[PSS/PAH]2) deposited on polyimide (PI) films was controlled by adjusting pH condition of micellar solutions, which influence molecular interaction between carboxylic acid in the PAA coronas and amine group in PAH located at the outmost layer on substrates. Since the Au nanoparticles in the micellar structure can provide etching resistance, only the polymer layers underneath Au nanoparticles remain intact during plasma treatment. After CF4 plasma etching, well-ordered and free-standing PI nanotips arrays were obtained on a 2-inch substrate. |
