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.
