The electrical conductivity, environmental stability, and surface properties of pristine polyanihne can be improved by synthesizing nanocomposite with large surface area materials such as carbon nanofibers [30]. Polyaniline/carbon nanofiber nanocomposite can be prepared by one-step vapor deposition polymerization [31]. In vapor deposition polymerization, a reactor consisting of two connecting flasks are used. In one chamber, the carbon nanofibers soaked in initiator are taken and the other chamber is equipped with a seahng apparatus. Then vacuum is appHed inside the chamber followed by the addition of liquid aniline monomer to the second chamber is carried out. The chamber is heated at low temperature in order to vaporize the anihne monomer. This process can continue... 

Non-destructive surface-functionalization of carbon nanofibers can be achieved by using poly(3,4-ethylenedioxythiophene) (PEDOT) since PEDOT is an electron donor and carbon nanofiber is an electron acceptor [40]. PEDOT/carbon nanofiber nanocomposites can be prepared by chemical polymerization process. This includes an initial adsorption of EDOT monomers on the carbon nanofibers, which is followed by the polymerization process. The adsorption of monomers on the fiber surface occurs due to the electrostatic n-n interaction. PEDOT poly(styrenesulfonate) (PEDOT PSS)/carbon nanofiber bilayer system is used particularly for electrode applications [41]. Such bilayer systems can be easily prepared with dip-coating technique.The advantage of dip-coating is that only a small amount of polymer will be adsorbed on the carbon nanofiber surface and hence nanometer thick coating is achievable. The surface area of electroactive materials can be enhanced in such bilayer systems prepared with carbon nanofibers. 

Carbon Nanotube and Carbon Nanofiber Nanocomposites. The discovery of single-wall carbon nanotubes (SWNT) has renewed focus on composites with SWNT, multiwalled carbon nanotube (MWNT) and carbon nanofiber (CNF) reinforcements, together referred to as ID Nanocarbon composites (39). These constituents offer promise for new lightweight materials with incredible mechanical, electrical, and thermal properties. ID Nanocarbon materials are envisioned as multifunctional materials, eg single materials used for structures as well as electrical and/or thermal conductors. One example is electronics in a space satellite that need to be lightweight and mechanically supported, have the excess heat dissipated, and be protected from electromagnetic interference (EMI). Other examples are structures that are also batteries and structures that store hydrogen for fuel cells. 

Chitosan- and water-soluble chitosan-cellulose nanofiber nanocomposite films were prepared by a simple and green procedure based on casting water (or 1% acetic solutions) suspensions of chitosan with different contents of NFC (up to 60%), and BC (up to 40%). The transparency of the films obtained indicated that the dispersion of the NFC and BC into the chitosan matrices was quite good. The nanocomposite films prepared with BC showed higher transmittance than the corresponding films prepared with NFC, because of the higher purity of BC.

An example of a deformation test of a nanofiber nanocomposite is illustrated in Fig. 9.12. The PMMA/Na-MMT nanofiber nanocomposite shows a porous structure (Fig. 9.12(a)). Early in the deformation process, the electrospun fiber will be slightly elongated along the fiber axis due to stress concentrations caused by the nanopores, which leads to a reduction in the fiber diameter (Fig. 9.12(b)).

The mechanism of flammability reduction for polymer nanotube and nanofiber nanocomposites (Chapter 10) is similar to that for clays a nanofiUer-rich surface or barrier forms, which slows the rate of mass loss and therefore the rate of heat release. There is little reduction in the total heat release, indicating that the carbon nanoflbers and nanotubes only reduce the flammability of the...
