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 (no) 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.
