This paper presents the effect of nanoparticle concentration on the performance of hybrid polymer (P-DSBT)/Zinc Oxide (ZnO) thin layers. For studying the morphology, the structure and the optical behavior of the different synthesized nanocomposites, FTIR transmission spectra, scanning electron microscopy (SEM), Transmission electron microscopy, and X-ray diffractometry (XRD) were used to characterize ZnO nanostructures, atomic force microscopy, UV-Vis absorption, photoluminescence spectroscopies and contact angle measurement were used to characterize (P-DSBT)/Zinc Oxide (ZnO) nanocomposites. It has been shown that the RMS (Root Mean Square) roughness of the hybrid layers increases as a function of the percentages of ZnO in the matrix. A clear participation of nanoparticles in the nanocomposites absorption has been demonstrated in UV-Vis spectra with maintaining the absorption features of the polymer. A photoluminescence study at room temperature was been also carried out under optical excitation set as lambda = 375 nm. It was confirmed that when increasing the ZnO concentration in the polymer, a shift towards red was observed and the contact angle of the composite layers decreases progressively comparing with the pure polymer. Interestingly, this confirms that polymer and polymer-ZnO hybrid nanocomposites are well adherent to the contaminated free solid surface. (C) 2019 Elsevier B.V. All rights reserved.
