Particulate polymer composites with fibers are a very active area of development, particularly carbon nanotubes and nanofiber composites, and the new graphite and polymer composites [35]. This fact, combined with the continued interest in nancomoposites based in nanometric clays [36], suggests that improvements in mechanical properties of particulate and short-fiber polymer composite materials will continue to be reported.

High-tenacity fibers have been demonstrated by dry-jet wet-spinning of anisotropic solutions of cellulose triacetate, but a product has not yet been commercialized [113,114], Nanofiber composites have been demonstrated by electro-spinning dilute cellulose acetate and triacetate solutions. These composites have exceptionally high specific surface area, and exciting new applications are envisioned [115], There are many new specialty applications, and research is continually finding new applications that take advantage of the unique balance of properties of cellulose acetate [107,109,110,116],...

Conductivity measurements were realized using broadband dielectric spectrometer. Nanofiber mat samples were prepared with the area of 4 cm for measurement As a result, conductivity values increased with an increase of PEDOT-PSS content at high frequency. Figure 5.19 shows the conductivity changes with the increase of the CP in the nanofiber composite.

The effects of poly(vinyl alcohol) and CdS quantum dots on the photoluminescence of PPV nanofibers have been assessed [90]. The nanofiber composites were fabricated by coupling a self-assembly method and an electrospinning method. 

Acids can act as dopants for polyaniline therefore, if the nanofibers are first doped with these acids, and subsequently exposed to the metal ions, precipitates should be formed on the surface of the nanofibers, leading to inorganic-polyaniline nanofiber composites. This idea has been applied in Section 7.3.5 to improve the detection of H2S. Another possibility is to use nanofibers as nucleation seeds to collect inorganic nanoparticles from supersaturated solutions [148].
