Abstract

We propose a one-step nanopatterning method where liquid monomers are polymerized directly with an electron beam under an atmospheric pressure. The method allows precise positional control of an electron beam that induces electropolymerization based on an anodic oxidation only in the irradiated areas. Various versatile conjugated polymers, including polypyrrole, polyaniline and poly(3-hexylthiophene), have been directly polymerized from monomers without solvents and patterned by our one-step nanopatterning method. Vertically oriented arrays of nanorods several hundred nanometers in diameter with an aspect ratio (height to diameter) of around two were fabricated.

摘要

我们提出了一种一步纳米图案化方法，即在大气压下，液态单体直接通过电子束进行聚合。该方法能够对电子束进行精确的位置控制，这种电子束仅在照射区域基于阳极氧化引发电聚合反应。包括聚吡咯、聚苯胺和聚（3-己基噻吩）在内的各种通用共轭聚合物已在无溶剂条件下由单体直接聚合而成，并通过我们的一步纳米图案化方法形成图案。制备出了直径数百纳米、长径比（高度与直径之比）约为2的垂直取向纳米棒阵列。
