“…The micrograph of MN25 contains white patterns due to the accumulation of charges on the electrolyte's surface. This owes a rapid increase in the number density and mobility of the ions from Table 7 67,68 . With further inclusion of salt, that is, for MN30, the formation of ion aggregates can be observed from the SEM micrograph of MN30, which agrees with the XRD analysis 69,70 .…”

Magnesium ion conducting solid polymer electrolyte films are prepared with biodegradable methyl cellulose and Mg(NO3)2.6H2O by solution casting method. FTIR spectrum of the films confirmed the interaction between the polymer host and the metal salt. FTIR deconvolution gives a clear picture of the percentage of free ions with the salt concentration variation. Structural modification of the polymer upon salt doping are studied with XRD analysis. Glass transition temperature of the pristine film is found to increase with the concentration of the salt, which is attributed to an increase in the coordination between Mg+2 and oxygen atoms of the polymer matrix and formation of transient crosslinks. TGA analysis accounts for the thermal stability of the electrolyte films. The electrical properties of the films have been analyzed, and the values of ionic conductivities of the films were calculated. Electrolyte film with 25 wt% of the salt, which is highly amorphous, is found to have the highest room‐temperature ionic conductivity of 1.02 × 10−4 S cm−1. SEM micrographs show variation in the surface morphology of the electrolytes with the variation in the concentration of the salt. The films' electrochemical stability window and ionic transference number are calculated to find the suitability for energy storage applications.

In recent years, bio‐based polymers have emerged as an alternative to petroleum‐based polymers in various industries. The bio‐based materials are made from raw materials originating from natural sources, such as starch, cellulose, chitin, or bio‐degradable synthetic polymers (i.e., polycaprolactone and polylactic acid). In spite of several desirable properties of biodegradable polymers, for example, fully renewable, non‐toxic. Some properties like melt and impact strength, thermal stability, permeability, and so forth, still do not meet the demands for end‐use applications. One way to improve the properties of biopolymers and greatly enhance their commercial potential is to incorporate nanosized reinforcement in the polymer. The access of nano‐carriers to smart polymeric and bio‐materials are limited by polymerization methods. Bio‐polymers are considered an alternative to petroleum‐based fibers. These are directly produced by organisms. Smart nanoparticles are used in different medicines and their applications are size‐dependent. Among the different techniques used for sensitivity, selectivity, and interactions among the nanoparticles. More so, different approaches were found for polymerization. Methodologies such as the preparation of nano‐gels, bio‐degradable, and bio‐polymers manufacturing in the pharmaceutical field are discussed in detail. Their applications, properties in gene delivery, smart imaging, and multivalency approach are also highlighted.

“…2 Generally, supercapacitors are eco-friendly in nature and the polymer electrolytes which are used in between the electrodes are generally of alkali metals which are usually dissolved in organic polymers where the cations of the polymers interacts with the host of the polymer and hence increases the conductivity. 3 The ion-conducting polymer electrolyte provides low equivalent series resistance and hence increases high specific power of the supercapacitor. In recent times, the solid polymer electrolytes are considered to be the most promising than liquid electrolyte because of its high ion diffusion, good mechanical stability and high ionic conductivity (in the range of 10 −2 –10 −4 Scm −1 ).…”

In this paper, we have used polymer polyethylene oxide as a host matrix and novel electrolyte ionic liquid 1-ethyl-3-methylimidazolium tricyanomethanide as an dopant to increase ionic mobility. Different characterization techniques like Electrochemical impedance spectroscopy, dielectric measurement, Fourier transform, X-ray diffraction, polarized optical microscopy, thermogravinometric analysis were used to identify the electrical, optical, structural and thermal properties. A laboratory scale supercapacitor has been fabricated using optimized solid polymer electrolyte film as an electrolyte and porous carbon derived from corn starch which shows a specific capacitance 13.6 F/g at 50 mV/s scan rate.
