Surface Modification of Carbon Nanotube Networked Films with Au Nanoclusters for Enhanced Gas Sensing Applications
Figure 6
Comparison of NO2 mean sensitivity of the MWCNT chemiresistor, unmodified and
Au-loaded of 5 and 10 nm, as a function of sensor temperature in the range of
100–200°C. The MWCNTs
thickness is about 250–300 nm and the
nominal thickness of Co growth-catalyst is 6 nm. The exposure time is 10
minutes.
