Synthesis and Micro hardness Studies of Polymer Nanocomposites of ZnS with PVK

Abstract The synthesis and microhardness studies of ZnS with PVK ((Poly N-Vinylcarbazole) nanocomposites are presented. thin films was form different loding in using chemical rout method characterized them SEM (Scanning Electron microscope), XRD (X-ray diffraction), AFM (Atomic Force Microscope) study their mechanical properties. shows have cubic nanocrystals structure, particle size about 3 to 12 nm. Broadening line the formation amorphous compound. SEM, images reveal clustering particles within 10 100 These three respectively increases loading PVK. on pure helps us understand modification properties due inter- intra- molecular interactions. It is seen that exhibit lower value as compare minimum for highest (50% ZnS) For each at first, load after that, beyond particular load, it obtain a saturated value, so can be say samples fully strain-hardened this load. micro hardness also corresponds frictional force. With increasing coefficient friction decreases force linearly Therefore, change Vickers number (Hv) curvilinear
