• conductivity of films Free-standing films were prepared by evaporative casting and vacuum filtration of KC–CNT dispersions. All films exhibited linear I–V characteristics, i.e., ohmic behaviour (Figure 5a). The total resistance (RT) increased with channel length (Figure 5b), and was found to scale linearly

• dispersions. The lines in (c) and (d) are fits to Equation 1 and Equation 2, respectively. (a) I–V characteristics for KC–CNT (channel length 2 cm) and (b) resistance as a function of length for KC–CNT composite films prepared by evaporative casting and vacuum filtration of KC–CNT dispersions.

• , CO: MKS 1479A, 0–100 sccm). The reaction chamber is connected to the analysis chamber by a quartz capillary with an inner diameter of 3 mm. At the lower end of the capillary, which reaches into the reaction chamber, a small cylindrical flow restrictor (channel length 3 mm, inner diameter 50 µm) is
