Research is conducted
that related to the preparation and characterization of solid polymer
electrolyte based on carboxymethyl chitosan, ammonia nitrate and ethylene
carbonate. The potential of carboxymethyl chitosan as a green polymer
electrolyte has been explored. Chitosan is a natural biopolymer which can be
obtained from partially deacetylated derivative of chitin. Chitosan react with
monochloroacetic acid to form carboxymethyl chitosan. The solid films were
prepared by solution casting technique with ammonia nitrate and ethylene
carbonate. Characterization of carboxymethyl chitosan – 30% wt. ammonia nitrate –
ethylene carbonate at the weight percentage of different plasticizers were carried out by using infrared spectroscopy analysis
(FTIR) analysis in order to study the changes in functional groups and
structural of carboxymethyl chitosan. The changes in shifting of wavenumbers
confirmed that there is an interaction between the ion of ammonia nitrate and
ethylene carbonate. Scanning electron microscope are used to study the
morphology of the film samples. Morphological observation determine whether the
blends were homogenous and no phase separation occurred. The presence of
amorfus and crystalline structure of the film samples can be determined by X- ray
diffraction. The conductivity in the film samples can be calculated through
electron impedance spectroscopy (EIS). Solid polymer electrolyte based
on carboxymethyl chitosan as host polymer and ammonium nitrate (NH4NO3)
as a complexing salt and ethylene carbonate were prepared by solution casting
technique. The highest ionic
conductivity value achieved by carboxymethyl chitosan – 30% wt. ammonia
nitrate salt – 25% wt. ethylene carbonate in room temperature was 3.86 x
10-3 S cm-1 which
characterized by AC impedance spectroscopic analysis.
