Catalyst-Free Vapor-Phase Method for Direct Integration of Gas Sensing Nanostructures with Polymeric Transducing Platforms

Figure 2

SEM and TEM imaging of tungsten oxide films with NNs-like morphology deposited on the polymeric transducing platform; (a) displays the film morphology from the top at low and high magnification, (b) displays the cross section of the films, (c) shows a pair of NNs removed from the polymer by sonication, and (d) shows the selected area electron diffraction of a NN.
