Synthesis and optical properties of polyvinylidene difluoride nanocomposites comprising MoO3/g-C3N4

he present study describes the optical properties for prepared polymer nanocomposites of PVDF at different content of MoO 3/gC 3 N 4. The structural properties of polymer films were analysed via XRD, FTIR and ESEM techniques. The XRD diffraction patterns of PVDF with different concentrations of MoO 3/gC 3 N 4 have two characteristic peaks at 2 θ= 18.4° and 20.3° where first peak was assigned to α-phase, while last peak was attributed to β-phase. The ESEM micrographs of PVDF-MoO 3/gC 3 N 4 nanocomposites have shown smooth surface topography. According to the UV–visible absorption spectra, the UV absorption of PVDF was increased when adding MoO 3/gC 3 N 4 nanoparticles where distinct peak was appeared in the UV region at 310 nm and its edges become more intense and moved towards higher wavelength after MoO 3/gC 3 N 4 incorporation. The optical values of (E dir) and (E ind
