Grafting and Patterned Grafting of Block Copolymer Nanotubes onto Inorganic Substrates
journal contribution
posted on 2006-12-13, 00:00 authored by Kyoungmoo Koh, Guojun Liu, C. Grant WillsonChemical patterning of inorganic substrates by soft lithography has enabled various high-tech
applications and cutting-edge fundamental research. In this paper, we report on methods for the grafting
and patterned grafting of block copolymer nanotubes onto glass and mica surfaces. Under optimized
conditions the density of such grafted nanotubes can be high, and most of the grafted tubes are in a standing
position even after solvent evaporation. Surfaces modified with exotic reagents such as block copolymer
nanofibers or nanotubes may find applications in biosensing, etc.
