Silver/polypyrrole/polyacrylonitrile composite nanofibrous mats were obtained by applying coating method. AgN03/PAN mats were prepared by electrospinning and the mats were placed into the boiling mixture of pyrrole and toluene. Then the pyrrole was oxidized by silver ions, leading to PPy and elemental Ag. 

Figure 8.6 shows the TEM images of silver/polypyrrole/ polyacrylonitrile composite nanofibrous mats prepared. It was reported that low AgN03 content could decrease the diameters of the Ag/PAN fibers and higher AgNOs concentration led to increase in the diameters of the hybrid fibers due to the high content of the solute in the electrospinning solution. ...

A polymer solution with a concentration of 15 wt% was prepared by dissolving polyacrylonitrile (PAN) in DME PAN solution in DMF was loaded into a 1 ml syringe. A modified electrospinning system consisting of two syringe pumps was used to produce bulky nanofibre mats. The experimental setup of this electrospiiming procedure is shown in Figure 2.4.

Most recent secondary lithium batteries use carbon as its anode, replacing metallic lithium found in primary batteries. Carbon anode provides greater cell life with safety and low cost however, it also has lower cell voltage, rate capability, and specific charge (theoretical capacity of 372 mA h g ). For the improvement of these specific properties, scientists have studied various nanofibrous anode materials with improved performance with respect to the above parameters. A comparison of specific capacities of various modified and unmodified carbon nanofiber (CNF) anodes is presented in Fig. 3.3. Kim et al. prepared CNFs by combining electrospinning and thermal treatments. Due to the particular nanotexture, these polyacrylonitrile...

Using a microfluidic device as the nozzle and putting two polymer solutions into the same microfluidic channel side-by-side, Lin et al. (2005b) have electrospun the side-by-side bicomponent nanofibres successfully (Fig. 5.13). The side-by-side fibre morphology can be clearly proved by selective removal of one of the polymer components from the nanofibres. As shown in Fig. 5.14b, when the polyurethane moiety is removed from a polyacrylonitrile-polyurethane (PAN-PU) bicomponent nanofibre, the residual PAN moiety retains its fibrous structure, except that one side is removed from the fibre.
