Doped polypyrrole/functionalized multi-walled carbon nanotubes composites were synthesized via in situ oxidative polymerization in an acidic medium, producing 2D films. The surface morphology of the thin film was characterized by computing the crystalline size and shape, and XRD analysis shows a triclinic crystal structure with space group P (1) over bar. The optical properties and structural parameters of the nanotube composite thin films suggest their potential for polymer solar cell applications.
Doped polypyrrole/functionalized multi-walled carbon nanotubes composites were synthesized in an acidic medium using an in situ oxidative polymerization route. FeCl3 was utilized as an oxidizing agent and sodium dodecyl sulfate as a surfactant to produce 2-dimensional films. Thin films were fabricated from polypyrrole/functionalized multi-walled carbon nanotubes composites using the thermal evaporation technique and are inspected by various methods. The surface morphology of the thin film is characterized by computing the crystalline size and shape. The XRD study of [PPy] and [PPyCNs](NC) as-deposited thin films showed that these polymers are merely a triclinic crystal structure with a space group P (1) over bar. The crystallite size (D) value average is 74.24 nm for [PPyCNsF](NC). The direct energy gap values are decreased from 2.68 to 1.93 eV for [PPy] and [PPyCNs](NC) as-deposited thin film, respectively. The optical features of the thin film were investigated. The optical constants and optical conductivity for the nanotubes composites were figured and interrelated by using experiment and TDDFT-DFT/DMOl(3) simulation methods. The structural and optical parameters of the simulated nanocomposites as single isolated molecules are in reasonable agreement with the investigational work. The nanotube composite thin films exhibited encouraging results to be a worthy applicant for polymer solar cell requests.
