Artificial nanostructured fillers are carbon nanofibers or nanotubes (CNT) and carbon black, which can act as reinforcements and which lead to an improved electrical conductivity of the compound. Nanostructured silica can be used as an antistick additive and nanosized silver particles exhibit an antibacterial effect when added to polymeric compounds. 

There are no reports about PANI composites with oxides of silver and gold because of the high redox reactivity of these oxides (e.g., Ag O and Au O can oxidize PANI), while PANI composites with copper oxides are known. Electrodeposition of mesoporous bilayers of PANI supported Cu O semiconducting films from lyotropic liquid crystalline phase has recently been reported by Xue et al. [16]. The control of size, morphology, and conductivity of PANI nanofibers (PANI-NFs) in PANI-NFs/CuO nanocomposites (Figure 2.1) was achieved by systematic variation of CuO loadings during the oxidative polymerization of aniline with mixture of oxidants [ammonium peroxydisulfate (APS) and sodium hypochlorite] in an acidic aqueous solution [17]. 

Antibacterial membranes with a multicomponent system containing Ag, AgBr, Ti02, and hydroxyapatite as four active components were used to obtain more efficient antibacterial activity. Additionally polyurethane nanofiber webs containing silver nanoparticles using the electrospinning technique were obtained with the stability of nanoparticles after washing cycles... 

When AgNOs was used in the rapidly mixed reactions, it took many days to observe the green color of doped polyaniline. The polymerization rate can be greatly enhanced by UV irradiation (Figure 7.40) and polyaniline nanofibers were obtained with highly dendritic silver microcrystals.

Isothermal and non-isothermal crystallization studies showed that the presence of nanofiller (multiwall carbon nanotubes, silver nanoparticles, nanodiamonds and copper-nanofibers) caused enhancement of crystallization rates and that the most effective nucleation was achieved using MWCNT. The crystals of a-type dominated, except in case of the sPS/MWCNT nanocomposite in which mairdy P-type crystals appeared. ...
