这封信报道了在有机聚合物基底上排列的单壁碳纳米管（SWNTs）的柔性场发射体阵列。通过荫罩溅射金，在Ti涂覆的聚合物基底上图案化金电极阵列。然后使用硫醇化学在金电极上形成有机分子的自组装单层。通过酸处理制备的切割单壁碳纳米管连接到有机分子的末端。场发射测试表明，在发射电流密度为10 μA/cm ~ 2时，开启电场为3.88 V/μm。电流密度为1.6mA/cm 2，6V/μm。这种室温工艺适用于制造具有碳纳米管的柔性电子器件。
This letter reports on flexible field emitter arrays of single-walled carbon nanotubes (SWNTs) aligned on organic polymer substrates. An array of gold electrodes was patterned on the Ti-coated polymer substrate by sputtering gold through a shadow mask. A self-assembly monolayer of organic molecules was then formed on the gold electrodes using thiol chemistry. Cut SWNTs prepared by acidic treatment were attached to the end of the organic molecules. The field emission measurement showed that the turn-on field was 3.88 V/μm at the emission current density of 10 μA/cm2. The current density was 1.6 mA/cm2 at 6 V/μm. This room temperature process is suitable for the fabrication of flexible electronic devices with carbon nanotubes.
