Metal-organic frameworks (MOFs) are highly versatile materials because of their tunable properties. However, the typically poor electrical conductivity of MOFs presents challenges for their integration into electrical devices. By adding carbon nanotubes to MOF synthesis, a highly intergrown material with increased conductivity and chemiresistive sensing properties can be obtained. Here, we present a patterning technique to control MOF growth on predefined areas of one particular carbon nanotube. We found that electron beam pretreatment of -COOH functionalized multi-walled carbon nanotubes inhibits the growth of UiO-66 MOF on these multi-walled carbon nanotubes. By irradiating individual multi-walled carbon nanotubes, we show that MOF growth can be inhibited in predefined tube areas, creating MOF-free spaces on the nanotube. In this way, our method shows a possibility to pattern MOF growth on individual nanotubes.

功能化碳纳米管上局部控制的 MOF 生长
金属有机框架(MOF)因其可调特性而成为用途广泛的材料。然而,MOF 的导电性通常较差,这给它们集成到电气设备中带来了挑战。通过在 MOF 合成中添加碳纳米管,可以获得一种具有更高电导率和化学电阻传感特性的高度共生材料。在这里,我们提出了一种图案化技术来控制 MOF 在特定碳纳米管的预定义区域上的生长。我们发现-COOH官能化多壁碳纳米管的电子束预处理抑制了UiO-66 MOF在这些多壁碳纳米管上的生长。通过照射单个多壁碳纳米管,我们发现 MOF 的生长可以在预定的管区域受到抑制,从而在纳米管上创建无 MOF 的空间。通过这种方式,我们的方法展示了在单个纳米管上形成 MOF 生长图案的可能性。
