제목 Freestanding 1D Nanostructure Arrays of a Variety of Functional Materials Using a Photo-Cleavable Cross-Linked Nanoporous Template
초록 High density arrays of conducting polymer nanodots and gold nanorods are fabricated by an electrochemical polymerization and deposition with a photo-cleavable cross-linked nanoporous template. Templates are prepared by self-assembly of silicon-containing block copolymers and a lithographic bilayer system. We introduced a dual responsive bottom layer into which the nanopatterns of block copolymer are transferred by oxygen reactive ion etching. Because the dual responsive layer becomes cross-linked by heating, it can be used as a hard template during the etching process. It becomes soluble again by chain scission upon exposure to light. Therefore, it can be easily removed by the lift-off process. Then, high density arrays of polypyrrole nanodots and gold nanorods are successfully obtained.
