Abstract EN
Blend of chitosan and spinach extract has been successfully prepared using acetic acid as a solvent medium to produce chitosan-spinach films.
The conductivity measurements showed that chitosan-spinach films for all ratios of 95 : 5, 90 : 10, 85 : 15, and 80 : 20 had better conductivity than the chitosan film.
The optical band gap reduced with the addition of the spinach extract into chitosan.
Chitosan-spinach film with the ratio of 85 : 15 gave the best electrical properties in this work with the conductivity of 3.41 × 10−6 S/m and optical band gap of 2.839 eV.
SEM-EDX spectra showed the existence of potassium, phosphorus, sulphur, iron, and oxygen in chitosan-spinach films.
AFM image showed that the surface morphology of the films became rougher as the spinach incorporated into chitosan.
The minerals which exist in spinach extract play a role in enhancing electrical properties of chitosan film.
