The conductivity and characterization of the plasticized polymer electrolyte based on the P(AN-co-GMA-IDA) copolymer with chelating group
چکیده انگلیسی
The effects of gel polymer with chelating groups on polymer matrix were been characterized by differential scanning calorimeter (DSC) and Fourier transform infrared spectroscopy (FT-IR). The mechanical properties were elucidated using an Instron instrument. The gel polymer, poly(AN-co-GMA-IDA), was made by the copolymerizing acrylonitrile (AN) and (2-methylacrylic acid 3-(bis-carboxymethylamino-2-hydroxy-propyl ester) (GMA-IDA), mixing the product with a plasticizer-propylene carbonate (PC). In a study on gel-type polymer electrolytes, lithium perchloride was doped into the gel polymer. FT-IR and 7Li solid-state NMR spectra elucidate the interactions between lithium ions and the unpaired electrons on the groups based on the gel polymer. Additionally, the 7Li solid-state NMR reveals that lithium ions are preferentially coordinated with the GMA-IDA segments. The glassy transition temperature (Tg) of the gel-type polymer electrolyte increases with the doping of LiClO4, indicating interactions among lithium ions, the plasticizer (PC) and the copolymer. The Arrhenius-like behavior of the conductivity reveals that the charge carries move in a liquid-like environment. The maximum conductivity in this investigation is 2.17 × 10−3 S cm−1. The GMA-IDA unit in the gel-type polymer electrolytes improves the dissociation of the lithium salt and the mechanical strength and conductivity of the electrolytes.
