研究目的
To improve the electrochemical and structural properties of polycarbazole by simultaneous electrodeposition of chitosan, aiming to enhance the electrical conductivity and structural properties of polycarbazole due to the presence of chitosan in the composite films.
研究成果
The study successfully synthesized polycarbazole/chitosan composite films with enhanced electrical conductivity and structural properties compared to pure polycarbazole. The presence of chitosan improved the film's mechanical properties, thermal stability, and electrical conductivity. The composite films showed potential for various industrial applications due to their improved properties.
研究不足
The study is limited by the solubility of chitosan in the electrolyte medium, which restricts the maximum concentration of chitosan that can be added. Additionally, the electrical conductivity values achieved are in the range of semiconductor conductivities, which may limit some applications requiring higher conductivity.
1：Experimental Design and Method Selection:
Electrochemical synthesis of polycarbazole/chitosan composite films was performed using cyclic voltammetry. The study involved varying the chitosan loadings to investigate its effect on the composite's properties.
2：Sample Selection and Data Sources:
The samples were synthesized on a Pt electrode, and characterization was done using various techniques including cyclic voltammetry, chronoamperometry, electrochemical impedance spectroscopy, FT-IR spectroscopy, thermal gravimetry, and scanning electron microscopy.
3：List of Experimental Equipment and Materials:
A Gamry Potentiostat (Reference 600) was used for electrochemical measurements. Materials included carbazole monomer, chitosan, acetonitrile, and lithium perchlorate.
4：Experimental Procedures and Operational Workflow:
The polymeric films were deposited on a Pt disk electrode by cyclic voltammetry after 5 cycles. The films were then characterized using the aforementioned techniques.
5：Data Analysis Methods:
The data from electrochemical measurements were analyzed to determine the electrical conductivity and other properties of the composite films.
