Biosynthesis of thin film derived from microbial chitosan for piezoelectric application
The aim of this paper was to synthesize and characterize microbial chitosan thin films for potential piezoelectric application. Microbial chitosan was derived from the Aspergillus oryzae fungus via extraction and deacetylation. Chitosan thin film was characterized for its surface morphol...

description |
The aim of this paper was to synthesize and characterize microbial chitosan thin films for potential piezoelectric
application. Microbial chitosan was derived from the Aspergillus oryzae fungus via extraction and deacetylation.
Chitosan thin film was characterized for its surface morphology, chemical properties, tensile strength, and
surface topography. For the potential application of chitosan as a piezoelectric material, its piezoelectric char-acteristics were presented in terms of its electromechanical coupling coefficient and piezoelectric coefficient. The
fabrication of the chitosan thin films was optimized via the one-factor-at-a-time (OFAT) method, where the
parameters were type of acid solvent, acid concentration and mixing time. The chitosan film prepared using
formic acid at a concentration of 0.25 M for 3 h of mixing time had the highest tensile strength (129.29 MPa),
electromechanical coupling factor (0.0045), and piezoelectric coefficient d31 (10 pC/N). The results obtained,
from the optimized fabrication of the chitosan thin film, were validated against fungal chitosan, and it was shown
that the properties of the thin film were comparable to those of commercial PVDF thin films. Therefore, the
prospect of using microbial chitosan thin film as wearable piezoelectric energy harvester or nano-generator is
promising. |
