“…Figure 5 shows Log vs. 1000/T for various blend polymer electrolytes. With the temperature rise, the conductivity increases with the temperature dependence of Arrhenius [34] type. The increase of DC conductivity with temperature can be ascribed to be the dissociation of ions and thus increase the number of charge carriers.…”

PMMA-Poly Methyl Methacrylate, PVdF-Poly Vinylidene Fluoride and Silver Nitrate (AgNO 3) based blend polymer electrolytes have been prepared by solution cast method. DMF (Dimethyl Farmamide) was used as a common solvent. These systems have been characterized by Scanning Electron Microscopy, Fourier Transform IR Spectroscopy and X-ray Diffraction for various ratios of prepared solid polymer electrolytes. DC ion conductivity has been studied for prepared electrolyte systems and the ionic conductivity of these systems showed Arrhenius behavior. It has been found that the electrolyte membrane's ionic conductivity rises with temperature. AC conductivity, electric modulus and dielectric studies have been investigated. The enhancement of conductivity was observed to be maximum for PMMA(70%):PVdF(30%):AgNO 3 (5%) (9.13 × 10-6 S/cm) and is attributed to decrease in crystallinity.

“…On dissolving a salt (proton donor) in the polymer matrix, the ionic conductivity of the host polymer is enhanced by the diffusion of mobile ions (H + ) from the salt which help conduction occur more frequently in the polymer system. 16,17 CMC will be doped with different contents of ammonium fluoride (NH 4 F), which acts as a proton donor. In the polymer−ammonium salt system, either NH 3…”

Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and transference number measurement (TNM) techniques were applied to investigate the complexation, structural, and ionic transport properties of and the dominant charge-carrier species in a solid biopolymer electrolyte (SBE) system based on carboxymethyl cellulose (CMC) doped with ammonium fluoride (NHF), which was prepared via a solution casting technique. The SBEs were partially opaque in appearance, with no phase separation. The presence of interactions between the host polymer (CMC) and the ionic dopant (NHF) was proven by FT-IR analysis at the C-O band. XRD spectra analyzed using Origin 8 software disclose that the degree of crystallinity (χ%) of the SBEs decreased with the addition of NHF, indicating an increase in the amorphous nature of the SBEs. Analysis of the ionic transport properties reveals that the ionic conductivity of the SBEs is dependent on the ionic mobility (μ) and diffusion of ions (D). TNM analysis confirms that the SBEs are proton conductors.

“…In case of pure PAN (Fig. , inset), FTIR peak at 3,626 cm −1 signifies the presence of OH groups of adsorbed moisture , while peaks at 2,931 and 2,243 cm −1 are due to CH and CN stretching vibrations, respectively. Moreover, FTIR peaks at 1,448 and 1,370 cm −1 are assigned to CH bending of CH 2 and CH groups, respectively of PAN.…”

Herein, one‐pot synthetic protocol is utilized to synthesize graphene oxide (GO) reinforced bovine serum albumin grafted polyacrylonitrile (BSA‐g‐PAN) microspheres through emulsifier‐free in situ emulsion polymerization route by using potassium persulfate (KPS) as initiator. The surface morphologies of pure PAN, BSA‐g‐PAN hybrid polymer, and BSA‐g‐PAN/GO hybrid bionanocomposites are observed through scanning electron microscope. Pure PAN shows the self‐assembled cauliflower like morphology which is found to be structurally interfered due to grafting between BSA and PAN. Moreover, the growth of cauliflower like morphology is influenced by the incorporation of GO platelets within BSA‐g‐PAN matrix, due to strong interfacial adhesion between GO and PAN. Transmission electron microscopy, X‐ray diffraction, and atomic force microscopy techniques are used to evaluate structural distributions of layered GOs within BSA‐g‐PAN chains. Due to filling up of microvoids of BSA‐g‐PAN structure by the GO layers, the oxygen permeability of the hybrid bionanocomposite is reduced by 22 folds with incorporation of only 3 wt% of GO. Moreover, the BSA‐g‐PAN/GO hybrid bionanocomposite shows significant antibacterial activities against bacteria such as S. aureus and E. coli. Primarily, thermal, gas barrier, biodegradability, antimicrobial, and mechanical properties of the synthesized hybrid bionanocomposites are studied to explore the hybrid bionanocomposite in packaging applications.
