本文描述了一种简单的无溶剂方法，用于在纸表面上制造化学电阻式气体传感器。该方法涉及在纤维素纤维上的传感材料的压缩粉末的机械磨损。我们通过沉积几种形式的碳的导电层（例如，单壁碳纳米管[SWCNT]，多壁碳纳米管和石墨）在不同的纸表面（图1，图S1）。基于单壁碳纳米管的传感器能够检测浓度低至百万分之0.5的氨气。
This communication describes a simple solvent-free method for fabricating chemoresistive gas sensors on the surface of paper. The method involves mechanical abrasion of compressed powders of sensing materials on the fibers of cellulose. We illustrate this approach by depositing conductive layers of several forms of carbon (e.g., single-walled carbon nanotubes [SWCNTs], multi-walled carbon nanotubes, and graphite) on the surface of different papers (Figure 1, Figure S1). The resulting sensors based on SWCNTs are capable of detecting NH3 gas at concentrations as low as 0.5 part-per-million.
