“…This increase in size may be attributed to the nanopar ticles of Fe 2 O 3 , which are coated with PANI and resulting in increase of nanocomposites size. The same behavior was also reported for PANI/NiO composites [53,54].…”

Nanocomposites of polyaniline with Fe 2 O 3 particles have been synthesized by chemical oxidative polymerization method by increasing the weight percentage of Fe 2 O 3 . The powder X ray diffraction tech nique was employed to study the structure and crystallinity of the synthesized nanocomposites. The strong interaction of polyaniline with Fe 2 O 3 particles was confirmed using FTIR technique. It was shown that poly aniline is dispersed into Fe 2 O 3 particles successfully by in situ polymerization and therefore the degree of crystallinity increased due to crystalline structure of Fe 2 O 3 particles. According to SEM and TEM data, most of Fe 2 O 3 particles were coated with polyaniline and those nanocomposites have formed a network during the polymerization process as well. Electrical conductivity of polyaniline containing 5 wt % of Fe 2 O 3 was higher among all other composites and even than PANI.

“…The second step, 150e300 C, is ascribable to loss of bound water molecules acting as secondary dopant. Finally, between 400 and 600 C, it is possible to observe the oxidative degradation of PANI chains [68,69]. Nanodiamonds are well-known to be thermally stable.…”

In this work, a polyaniline honeycomb nanocomposite is synthesized via chemical route and Breath Figure technique and characterized through Fourier Transform Infrared, X-ray diffraction, thermogravmetric analysis, and morphological analysis (SEM and TEM). The DC, AC conductivities, and Mott's VRH parameters have been measured in the temperature range from 303 to 373 K and frequency range from 20 Hz to 1 MHz. The DC conductivity of the nanocomposite enhanced and AC-conductivity is attributed to overlapping large polaron tunneling (OLPT) mechanism. The composite is tested for supercapacitor properties. A specific capacitance of 554 F/g and energy density of 76.9 Wh/kg at 1 A/g current density, and high power density of 2.00 kW/kg at 4 A/g indicates more feasibility of the redox process. Electrochemical impedance spectroscopy and cyclic voltammetry reveals that the nanocomposite is an excellent supercapacitor electrode material.In the last few decades, chitosan biopolymer is extensively used in industry for various applications like sensor, battery, supercapacitor, etc. 15 CS is nontoxic; it has excellent film forming ability with good adhesion, mechanical strength, high permeability, Additional Supporting Information may be found in the online version of this article.
