Self-Organization of ZnO Nanoparticles on UV-Curable Acrylate Nanocomposites

[摘要] Our work focused on synthesis and investigation of nanoparticles role in structuring of homogenous nanocomposite based on ZnO nanoparticles in UV-curable monomers mixture. Due to strong interaction between nanoparticles surface and polymerizable carboxylic acid, nanoparticles were distributed homogeneously, and density of nanocomposite increased also in comparison with pure polymer matrix. Light scattering, plasticity, and water sorption non-monotonically depends on the concentration of nanoparticles concentration. UV-curable active matrix polymerization on the surface of ZnO nanoparticles was investigated using IR spectroscopy. The set of structural modifications of polymeric nanocomposites were observed by ASM, light scattering, Brinell hardness, and water sorption.Suggestions that the nanoparticles in the polymerization process play the role of photocatalysts and provide structuring effect on the nanocomposite were discussed.
