| Abstract: | Nano-TiO2/waterborne polyurethane composites were prepared by means of solution blending.The mechanical properties and thermal stability of the composites were affected by nano-TiO2.The effect rules of nano-TiO2 to the composites were explained reasonably.Antibacterial activity of the composites against Escherichia coli and Staphylococcus aureus was also tested.The results revealed that the antibacterial activity enhanced with the increasing nano-TiO2 content. |
