These results recommend the suitability of the fabricated polymer electrolyte for lithium ion battery system. Linear sweep voltammetry shows that the highest conducting sample is electrochemically stable up to 2.36 V without SN, and it is 3.1 V with SN addition. Transport parameters of diffusion coefficients and mobility of cations and anions are also in tune with the conductivity results. Transference number analysis also reveals that the cause of conductivity is primarily due to ions with the highest ionic transference number of 0.92 (Wagner’s method) and cationic transference number of 0.58 (Bruce and Vincent method) for the highest conducting plasticized sample. The inclusion of 0.3 wt% of SN into this polymeric system has improved the value of ionic conductivity to 3.33 × 10 −3 S cm −1 at ambient temperature, and the activation energy is found to be very low for this concentration. The highest ionic conductivity at room temperature is 3.57 × 10 −4 S cm −1 for the film composition of 1.0 g i-carrageenan/0.5 wt% LiClO 4. The obtained biopolymer electrolytes are characterized by X-ray diffraction, Fourier-transform infrared, differential scanning calorimetry and AC impedance studies. Succinonitrile (SN) plastic crystal has been used as an additive to optimize the conductivity of i-carrageenan biopolymer electrolytes. Chem.A non-toxic and bio-active natural polymer electrolyte iota-carrageenan (i-carrageenan) with LiClO 4 has been prepared by conventional solution casting technique.

The prepared aerogels had high removal efficiency with selectivity order Co 2+ > Cu 2+ > Mn 7+ > Cd 2+ > Cr (VI). sulfate and amine) was revealed via the high ability of the aerogels to remove the cations and oxyanions in a similar manner. The synergetic effect for the presence of the chelating groups with different natures (i.e. The adsorption behavior of the aerogels was evaluated for Cr (VI), Co 2+, Cu 2+, Cd 2+, Mn 7+, and Alphanol fast blue dye. These aerogels are environmentally safe, eco-friendly and cheap. The nitrogen contents of the aerogels were determined using the Kjeldal method. The surface area and porosity were calculated using Brunauer, Emmett, and Teller (BET), Barrett, Joyner and Halenda (BJH) equations. The prepared magnetic nanoparticles and aerogels were fully characterized using particle size analyzer, X-ray diffraction (XRD), vibrating Sample Magnetometer (VSM), FT-IR, SEM and energy-dispersive X-ray (EDX). A blank sample of chemically cross-linked Iota-carrageenan was prepared for comparison. ![]() Magnetic aerogels were prepared via physical cross-linking of Iota-carrageenan and polyamidoamine (PAMAM) dendrimer using different amounts of magnetic nanoparticles (1, 3 and 5%). ![]()
