Abstract: The title nano no/-acrylate composite emulsion was prepared via soap-free e- mulsion polymerization. Mechanism of polymerization for composite emulsion was discussed. The effects of dispersant and adding method of monomers on encapsulation were studied. It was shown by TEM that Zno nanoparticle was encapsulated in polymer phase. SEM result indicated that nano-zno particles were homo-geneously dispersed in the latex film. The UV resistant properties and antibacterial activity of composite film were also discussed. It demonstrated that coatings prepared with Zno/Pst -acrylate emulsion presented a perfect UV resistant property and antibacterial activity.

Key words: nano Zno, composite latex, UV resistant properties, antibacterial activity
