Abstract:
Capillary force lithography was applied to generate large area polymer patterns. A "grafting to" approach was used on the patterns to induce linear assembly of Pd nanocubes through electrostatic interaction. Pd nanoarrays with high density were subjected to a hydrogen gas sensing test. We demonstrated a feasible method to build up a miniature hydrogen sensor using self-assembly with micrometre Pd nanoarrays.
