From: Accelerating Gas Adsorption on 3D Percolating Carbon Nanotubes
Adsorption kinetics in SWCNT-network and SWCNT/F8T2-composite.
(a,b) Gas response of the SWCNT-network and the 13-nm-thick SWCNT/F8T2-composite, respectively, with different Vg pulses. Only positive Vg pulses are shown here. Black arrows: time point for the sensor to be exposed to NO2. Colored arrows: the onset time points at which Id,off starts to increase. Delay in time from gas feeding to sensor response strongly dependent on Vg. (c,d) Dependence of 
on td for the SWCNT-network and SWCNT/F8T2-composite, respectively. Solid lines: fits results according to the first derivative of equation (3).
