SiO2 Nanodot Arrays by Selective Adsorption on Functionalized Block Copolymer Templates |
| 초록 |
The inherent variety of block copolymers makes their self-assembly an attractive means of creating such surfaces and they have been used as effective and versatile templates for many inorganic materials. Silicon oxide (SiO2) in particular has demonstrated tremendous promise in applications ranging from microelectronics to photonic devices. SiO2 nanodot arrays were fabricated by a selective interaction with functionalized block copolymer templates. A poly(styrene-b-acrylic acid/acrylic anhydride) (PS-b-PAA/PAN) thin film containing spherical nanodomains was used as a template to build nanoscopic silica structures. A PS-b-PAA/PAN thin film was prepared by the acid-catalyzed thermal deprotection of poly(styrene-b-tert-butyl acrylate) on an SU-8 resist containing photoacid generators. Aminopropyl-terminated PDMS was selectively adsorbed on carboxylic acid groups in spherical domains of PAA/PAN. SiO2 nanodot arrays were generated via calcination. |
