通过将碳纳米管分散在多巴胺溶液中并在室温下温和搅拌，可以很容易地在碳纳米管上涂覆一种活性生物聚合物-聚多巴胺(Pdop)。该涂层没有破坏纳米管的侧壁，通过调节反应时间、pH和温度，纳米管的厚度得到了很好的控制。由此得到的涂层是一种多功能平台，既可用于功能有机广告层，也可用于化学镀金属。在室温下，通过在HAuCl4溶液中的简单搅拌，在Pdop层上沉积了高浓度的金纳米颗粒。(C)2008爱思唯尔有限公司。保留所有权利。
Carbon nanotubes were easily coated with a reactive biopolymer - polydopamine (Pdop) - by dispersing them in a dopamine solution and mildly stirring at room temperature. The coating did not ruin the nanotube sidewalls, and its thickness was finely controlled on the nanometer scale by adjusting the reaction time, pH and temperature. The resulted coating is a versatile platform for both functional organic ad-layers and electroless metallization. A high concentration of gold nanoparticles was deposited on the Pdop layer, by simply stirring within HAuCl4 solution at room temperature. (C) 2008 Elsevier Ltd. All rights reserved.
