PEI-Functionalized Carbon Nanotube Thin Film Sensor for CO<sub>2</sub> Gas Detection at Room Temperature
In this study, a polyethyleneimine (PEI)-functionalized carbon nanotube (CNT) sensor was fabricated for carbon dioxide detection at room temperature. Uniform CNT thin films prepared using a filtration method were used as resistive networks. PEI, which contains amino groups, can effectively react wit...
