摘要: Abstract The anatase and rutile titanium dioxide (TiO 2 ) were prepared characterized by X-ray diffraction, transmission electron microscopy, scanning microscope UV–vis spectrophotometer. Then they introduced into waterborne polyurethane (WPU) to prepare hybrid films. effects of TiO on the structure properties films comparatively studied. results showed that incorporation nano-TiO WPU can highly improve UV protection ability, mechanical property, photocatalytic ability antifungal capacity Moreover, incorporated exhibited best capacity. However, had higher tensile strength at appropriate content, which may be resulted from special asymmetric acicular sharp . indicated cooperation give performances polymer–TiO nanocomposites.
