A facile method to prepare g-carbon nitride/poly(vinyl alcohol) nanocomposite films with remarkable optoelectrical properties: Laser attenuation approach

Nanocomposites consisting of polyvinyl alcohol (PVA) and graphitic carbon nitride nanoparticles (g-C3N4) were fabricated by solution casting technique. XRD has shown that the semicrystalline PVA structure is greatly affected by the incorporation of g-C3N4, which is confirmed by SEM images. Optical characteristics are investigated at room temperature within the wavelength range (200–1500 nm). The effect of g-C3N4 content on the optical band gap...
