“…The conductivity increases with incorporation of TPAI, declines a little at W TPAI = 0.05, continues to increase until it reaches a second maximum at W TPAI = 0.15, then declines again for W TPAI > 0.15. A similar conductivity trend has been reported by Xie et al . The occurrence of the first maximum of conductivity may be attributed to the two competing effects brought about by the salt.…”

Poly(methyl acrylate) (PMA)-tetrapropylammonium iodide (TPAI) and poly(vinyl acetate) (PVAc)-TPAI solid polymer electrolytes were prepared by solution casting method. DSC, FTIR, and conductivity results are reported. TPAI interacts with PMA and PVAc to form PMA-TPAI and PVAc-TPAI complexes. Formation of PMA-TPAI and PVAc-TPAI complexes are supported by the DSC and FTIR studies. Linear relationship for the dependence of glass-transition temperature, T g , on salt concentration allows the estimation of the complexation extent between polymer and salt. A greater extent of complexation for PMA with TPAI is observed and correlated with the FTIR results. The conductivities achieved at 15 wt % of TPAI for PMA and PVAc are 2.6 × 10 −11 and 1.3 × 10 −11 S cm −1 , respectively. Higher dielectric constant and lower T g of PMA result in higher number and mobility of ions, which lead to higher conductivity in accordance with σ = enμ. All-solid-state dye-sensitized solar cells (DSSCs) were assembled with PMA-TPAI and PVAc-TPAI electrolytes. DSSC efficiencies achieved for PMA and PVAc are 2.41% and 2.05%, respectively. Better performance of DSSC with PMA electrolyte is attributed to higher short-circuit current density, J sc , and lower recombination loss. Lower J sc , higher recombination loss, and degradation of counter electrode are the reasons for DSSC degradation.

“…In addition, CO 2 , H 2 O, and SO 2 gases released in the redox reaction between graphite and H 2 SO 4 /HSO 4 − can dilute the concentration of flammable gas in the flame [9]. Because of its excellent performance, EG is widely used as a flame retardant additive for polymer materials such as ethylene vinyl acetate (EVA) [10], polyolefin [11,12], acrylonitrile-butadiene-styrene (ABS) [13,14], epoxy resin [15], and silicone rubber [16]. However, the used EG is commodity, and it is prepared by using H 2 SO 4 as an intercalating agent, which makes the GIC usually contain high levels of sulfate and release more SO 2 gas during combustion.…”

In this study, three different sizes of tripolyphosphate‐modified expandable graphite (EGp) are prepared and incorporated into rigid polyurethane foam (RPUF) in order to obtain a flame retardant material with low density, good mechanical properties, and hydrophobicity. The influence of particle size on material combustibility, thermal stability, compression strength, pore cell structure, diathermancy, and hydrophobic property is investigated. Synergistic effect between the EGp and ammonium polyphosphate (APP II) is also examined. Results show the limiting oxygen index value and residue yield increase as the EGp size increases. On the contrary, the heat release rate and total heat release decrease as the EGP size increases. In addition, the chemical char formation effect of APP on RPUF is more important than the char formation of the graphite intercalation compounds. EGp and APP show synergistic effect in improving flame retardancy, thermal stability, and hydrophobicity. POLYM. ENG. SCI., 59:1381–1394 2019. © 2019 Society of Plastics Engineers

“…Grotthus mechanism of ion transport is well-accepted mechanism in many polymer systems. In this mechanism movement of ions are associated with the flexibility/movement of the polymer chains 30 especially having moieties to which ions are connected. For present system we may propose this mechanism as shown in Figure 5 in which Naþ is getting associated with hanging hydroxyl oxygen whose vibrational motion will assist cation movement.…”

A biopolymer based electrolyte system has been developed using NaI as dopant salt and Arrowroot starch as polymer matrix. Problem of fungal growth in such system has been removed by the addition of Glutaraldehyde (GA). The conductivity of the Arrowroot + NaI electrolyte system is of the order of 6.7 × 10−4 S cm−1. Starch without crosslinker GA seems to be highly unstable and prone to fungal growth whereas the GA crosslinked electrolyte is quite stable. Color of the material as well as its conductivity data indicate that presence of GA affects the salt dissociation and multiplets formation. Ionic transference number of system is ≥0.95 indicating that prepared system is ionic conductor/electrolyte. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
