Figure 5. (A) In-situ redox polymerization of pyrrole on CNTs@TrW. (B-D) Top-view SEM images of PPy@CNTs@TrW at different magnifications, showing uniform PPy coating on CNTs surface. (E-G) side-view SEM images of PPy@CNTs@TrW at different magnifications, showing a high amount of PPy nanorods aggregated on the cell wall surface. (H-J) Top-view and (K-M) side-view SEM images of PPy@TrW showing uniform PPy coating on the wood surface. The images show a limited amount of PPy aggregation on the TrW surface.
