“…All the composites showed that the graphenebased materials were covered with PIn because indole monomers can adsorb and grow on the surfaces of graphene-based materials. 40 For example, this phenomenon is illustrated in Fig. 1(d) and (e), which show the surface morphologies of cm-GO and the in situ cm-GO/dPIn composite, respectively.…”

Polyindole (PIn) nanoparticles were synthesized through an emulsion polymerization technique in this study and then examined as an anhydrous semi‐conducting electro‐responsive material. Their surface morphology and chemical structure were observed with high‐resolution scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. When dispersed in silicone oil, the electrorheological (ER) properties of the PIn particles were examined using a rotational rheometer with both steady shear and oscillatory tests under various applied electric field strengths with direct observation using an optical microscope. Flow curves of shear stress as a function of shear rate were well fitted using the Cho‐Choi‐Jhon model. Dielectric analysis was also performed to examine the permittivity and loss factor in relation to the ER effect. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46384.

“…Furthermore, the spectrum of PIn as shown in Fig. 3(c) displays the vibration at 734 cm −1 corresponding to the presence of C-H bond in the benzene ring of indole, the vibration at 1104 cm −1 due to stretching of C-N bond, whereas the bands at 1222 cm −1 and 1430 cm −1 are characteristics of the aromatic ring stretch vibrations in PIn 42 . It is to be noted that the spectrum of ZnO/PIn-MWCNTs nanocomposite given in Fig.…”

presently, one of the most important aspects for the development of enzymatic biofuel cells (eBfcs)is to synthesize the novel electrode materials that possess high current density, low open-circuit voltage (ocV) and long-term stability. to achieve the above attributes, lots of new strategies are being used by the researchers for the development of advanced materials. nowadays, nanomaterials and nanocomposites are the promising material that has been utilized as effective electrode material in solar cells, supercapacitors and biofuel cells application. Herein, we account for a novel electrocatalyst as electrode material that comprised Zno nanoparticles decorated on the surface of polyindole (pin)-multi-walled carbon nanotube (MWcnt), for the immobilization of glucose oxidase (Gox) enzyme and mediator (Ferritin). The PIn-MWCNT scaffold is prepared via in situ chemical oxidative polymerization of indole on the surface of MWcnt and assessed by myriad techniques. the micrograph of scanning electron microscopy (SeM) designated the interconnected morphology of MWcnts in the polymer matrix. X-ray diffraction spectroscopy (XRD) and Fourier transform infrared spectroscopy (FTIR), confirm the crystallinity and different functional groups available in the synthesized material, respectively. the electrochemical assessment demonstrates that the Zno/pin-MWcnt/frt/Gox nanobiocatalyst exhibits much higher electrocatalytic activity towards the oxidation of glucose with a maximum current density of 4.9 mA cm −2 by consuming 50 mM glucose concentration in phosphate buffer saline (PBS) (pH 7.4) as the testing solution by applying 100 mVs −1 scan rates. the outcomes reflect that the as-prepared ZnO/PIn-MWCNTs/Frt/GOx biocomposite is a promising bioanode for the development of eBfcs.Recently, enzymatic biofuel cell (EBFC) is a modern green renewable technology that can harness hidden electrical energy present in the chemical bonds of the replicate fuels, while catalyzing them with the assistance of redox enzymes as the electrocatalyst 1 . EBFCs are exploiting a large number of biological fuels such as lactate 2 , fructose 3 , starch 4 , and glucose 5 . Moreover, favorable operating conditions like ambient temperature 6 , mild pH 7 , and use of biological catalysts make EBFCs dominant over the traditional fuel cell, which in contrast, used noble metal catalysts (Platinum, gold, and silver), variable pH and working temperature range. Because of these characteristics, EBFCs has received immense attention as power generators in portable devices and automobiles 8 .Glucose oxidase (GOx) is a commonly utilized enzyme in EBFCs, owing to possess specificity towards the glucose fuel that is abundantly available as biomass in the surrounding as well as in the physiological fluid. Fascinatingly, utilization of biofuels, particularly glucose, has drawn special attention in powering various implantable medical electronic devices such as pacemakers 9 , miniaturized sensors 5 , transmitters 10 , and artificial ability to conduct nanocomposite while th...
