Preparation, Characterization And Application Of Polypyrrole-Chitosan Conducting Polymer Composite
Polypyrrole-chitosan (PPy-CHI) conducting polymer composite films were prepared by electropolymerization of pyrrole (Py) in the presence of chitosan (CHI) and ptoluenesulfonic acid sodium salt (P-TS) at room temperature. The PPy-CHI composite films were synthesized by electrochemical method on th...

| description |
Polypyrrole-chitosan (PPy-CHI) conducting polymer composite films were prepared
by electropolymerization of pyrrole (Py) in the presence of chitosan (CHI) and ptoluenesulfonic
acid sodium salt (P-TS) at room temperature. The PPy-CHI composite
films were synthesized by electrochemical method on the ITO glass surface from
different concentrations of pyrrole, CHI, and P-TS at different applied voltages. For
comparison purposes, film formed from chitosan in acetic acid (CA) by casting
method and PPy film without chitosan were prepared.
The electrical conductivity measurements revealed that the composite film prepared
from the solution containing 0.3 M pyrrole, 0.1 M p-TS and 0.7% (w/v) of CHI at 1.2
volt (against SCE) in 2 hrs, had the highest conductivity of 69.1 Scm-1 measured at
room temperature. The electrical conductivity measurement and the DMA results
showed the enhanced conductivity and mechanical properties of the prepared
conducting polymer composite films were due to the presence of CHI in the composite films. |
