Characterization of the dispersion of tetrapod-like nano-ZnO whiskers in acrylic resin and properties of the nano-composite coating system

Tetrapod-like nano-ZnO whiskers were prepared by physical method. For small size and surface effect of nano materials, aggregation tendency should be resolved before practical application. Hence, different dispersing methods were designed and examined. Nano-ZnO/acrylic resin composite coatings were prepared to form nano-functional coatings. It was observed that the composite with uniform distribution of nano-ZnO in the acrylic resin had multifunctionalities. Different treatment methods for tetrapod-like nano-ZnO whiskers demonstrate an intensified affect on the final functional effects of composite coatings. The coatings can be used for plastic materials, etc. Furthermore, the mechanisms of the functions were also analyzed for the sake of understanding.
