“…However, applications of PANI have been limited due to its low solubility in common organic solvents and its difficult processability [5]. This drawback can be overcome by the dispersion and formation of a conductive network of PANI nanofibers within conventional polymers, following different approaches such as melt blending by extrusion, solution/dispersion, in situ polymerization, and electrochemical polymerization [6]. In this work, the electrical and thermal properties of prepared PI/PANI composite films by in situ polymerization have been studied.…”

Polyimide/polyaniline nanofiber composites were prepared by in situ polymerization with various weight percentages of polyaniline (PANI) nanofibers. X-ray diffraction (XRD) and Fourier transform infrared spectra (FT-IR), proved the successful preparation of PANI nanofiber composite films. In addition, thermal stability of PI/PANI nanofiber composites was superior relative to PI, having 10 % gravimetric loss in the range of 623 °C to 671 °C and glass transition temperature of 289 °C to 297 °C. Furthermore, the values of the loss tangent tanδ and AC conductivity σAC of the nanocomposite films were notably higher than those of pure polyimide. The addition of 5 wt.% to 15 wt.% PANI nanofiber filler enhanced the activation energy of PI composites from 0.37 eV to 0.34 eV.

“…This and related information is given in Table 2. 4,15,34 Considerable anisotropy in structure and mechanical properties can be obtained, as was demonstrated for PDMS. 35 Specifically, the reinforcement is found to be significantly higher in the direction parallel to the magnetic lines of force.…”

“…4,8,9,14 It is also possible to polymerize conducting polymers such as polyaniline within polysiloxane matrices. 15 As is evident from Table 1, the method can also be used in a variety of polymers (organic as well as inorganic, nonelastomeric as well as elastomeric). Basic catalysts give precipitated phases that are generally well-defined particles, whereas the acidic catalysts give more poorly defined, diffuse particles.…”

The nanocomposites described here all involve polymers and were chosen because they are already of commercial importance, show some promise of becoming so, or simply seem interesting. The field is so broad that some topics are mentioned only very briefly, and there is considerable emphasis on the polysiloxane nanocomposites studied by the author's research group. Some are typically prepared using techniques very similar to those used in the new sol-gel approach to ceramics, with either the polymer or the ceramic being the continuous phase. Other dispersed phases include particles responsive to an applied magnetic field, intercalated or exfoliated platelets obtained from clays, mica, or graphite, silsesquioxane nanocages, nanotubes, dual fillers, porous particles, spherical and ellipsoidal polymeric particles, and nanocatalysts. Also described are some typical studies involving theory or simulations on such particle reinforcement. Experiments on ceramics modified by dispersed polymers are equally interesting, but there is less relevant theory. Many of the fields mentioned have become so vast that the approach taken here is simply to describe general approaches and characteristics of the composites, list some specific examples, and provide leading references (with some emphasis on studies that are relatively recent or in the nature of reviews).

“…First, the development of readily soluble forms of PANI through the use of functionalized counteranions has pointed the way to a multitude of combinations of dopant anions and cosoluble bulk polymers [6]. Other approaches such as blending of PANI electrochemically [7], in-situ chemical polymerization of aniline monomer in the presence of polymeric matrix [8], and dispersing of PANI in the melt of a thermoplastic polymer [9,10] have been introduced. The processing of doped PANI and host polymer in a single solvent as developed by Cao et al [11] produced blends with high electrical conductivities at relatively low loading levels of PANI salt.…”

Polyaniline/nylon 6 blends were prepared from formic acid as a single solvent with various weight ratios of polyaniline (PANI). The optical, structural, morphological, thermal, and electrical properties of these blends were investigated. Blend films with PANI protonated with sulfanilic acid (SA) as a new protonating agent showed higher conductivity and degree of protonation in comparison with unprotonated PANI. The PANI-SA/nylon 6 blend exhibited a percolation threshold at around 1.66 wt.% of PANI, whereas unprotonated PANI/nylon 6 blend appeared at round 10 wt.% of PANI. Schottky diodes based on PANI-SA and nylon 6 blend at different weight percentages of PANI were fabricated and characterized using Al as Schottky contact and Ag as an Ohmic contact.
