Structural, Electrical And Ion Transport Properties Of Natural Polymer Based Carboxylmethyl Cellulose Doped Ammonium Carbonate

Abstract

Conducting solid polymer electrolytes (SPE) has garnered much attention since it possesses great advantages especially polymer derived from natural sources. Current work aims are to develop and characterize SPE films formed from carboxymethyl cellulose (CMC) as the polymer host and doped with varying ammonium carbonate ((NH4)2CO3) concentration (1 wt.% - 11 wt.%) through solution casting techniques. The CMC-(NH4)2CO3 SPE were tested and analyzed by numerical analysis to determine the effect of (NH4)2CO3 in the CMC-(NH4)2CO3 SPE system. The CMC-(NH4)2CO3 SPE films structural analysis was conducted through X-ray diffractometer (XRD) for phase identification and Fourier-transform infrared (FTIR) for complexation confirmation. All CMC- (NH4)2CO3 SPE films show highly amorphous content with crystallite size ranging between 0.96 nm and 1.37 nm. IR vibrational analysis shows interaction mainly occur at 1591 cm -1 wavenumber due to C=O of carboxyl group of CMC interaction with H + of ammonium carbonate.
