Water-based carbon nanotube（CNT）is highly desirable for inkjet printing devices due to its environmentally benign and low-cost features.To improve the dispersion of CNT in water,oxygen-containing functional groups are introduced into the surface of CNT via an acid oxidation process.The CNT-based gas sensor is fabricated by inkjet printing,which shows a high sensitivity toward NO₂.The apphcation of inkjet-printed CNT in a printed RF antenna for wireless sensing is also discussed.
