Abstract Surface modification of ZnO nanoparticle with polyvinyl acetate was conducted through–plasma polymerization process. The surface morphology and structure of the functionalized ZnO nanoparticles were investigated. The influence of surface modification on optical properties was examined. The results indicated that a uniform layer with a thickness of 3–7 nm formed on the surface of the ZnO nanoparticles. The thin layer on the surface of the ZnO nanoparticles was found to be polyvinyl acetate (PVAC). Moreover, ageing test for two years indicated that the adhesion behavior between the organic VAC and the inorganic ZnO nanoparticles was good. In marked contrast to the uncoated ZnO nanoparticles, the surface modification resulted in significant decrease of PL intensity. UV/Vis spectra revealed that the PVAC–functionalized ZnO nanoparticles show strong absorption of UV light at wavelengths between 200 and 800 nm while the optical transparency in the visible region was slightly below that of the untreated ZnO nanoparticles.
