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.

摘要

毛细作用力光刻被应用于大面积聚合物图案的生成。在图案上采用“接枝到”的方法，通过静电相互作用诱导 Pd 纳米立方体的线性组装。高密度的 Pd 纳米阵列进行了氢气传感测试。我们展示了一种使用微米级 Pd 纳米阵列自组装构建微型氢气传感器的可行方法。
