Fabrication, optical, and surface characteristics of P(4-CAni)/g-C₃N₄ nanocomposite for optoelectronics

In this study, the poly 4-chloroaniline P(4-CAni) and the graphitic carbon nitride g-C₃N₄ were merged to prepare the new composite P(4-CAni)/g-C₃N₄ films using the oxidative chemical polymerization method. The optical and surface characteristics of P(4-CAni)/(g-C₃N₄) nanocomposites were investigated to explore their potential for optoelectronic applications. The X-ray diffraction confirms the effective fabrication of the composite P(4-CAni)/g-C₃N₄. The surface analyses confirmed the homogeneous embedding of thin g-C₃N₄ nanosheets within the P(4-CAni) matrix. The refractive index (n_o) increased from 1.13 for P(4-CAni) to 1.32 for P(4-CAni)/(g-C₃N₄), the dispersion energy increased from 1.17 to 1.89 eV, and the oscillation energy decreased from 4.4 to 3.59 eV. The incorporation of (g-C₃N₄) in the P(4-CAni) results in modifications in the optical characteristics. Because of the changes made to the structural and optical characteristics of the produced composites, the result from this study validates the usage of P(4-CAni)/(g-C₃N₄) in optical devices.
