摘要
采用十六胺作为表面修饰剂,通过一种简单易行的方法成功制备了纳米TiO_2微球.分别利用傅立叶红外光谱仪(FTIR)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)等表征手段对纳米TiO_2微球进行了结构和形貌表征.将制备的纳米TiO_2微球添加到水性聚氨酯基体(WPU)中,测试了其性能.结果表明,纳米TiO_2微球的添加显著提高了WPU的抗紫外线性能、耐水性和热稳定性等.
TiO2nanospheres were prepared by a simple and facile method with hexadecylamine as the surface modifiers,and their structure and morphology were characterized by Fourier transform infrared spectroscopy(FTIR),scanning electron microscopy(SEM)and transmission electron microscopy(TEM).The so-obtained TiO2 nanospheres were added into waterborne polyurethane matrix(WPU).The initiatory experimental results show that the ultraviolet resistance,water resistance and thermal stability of WPU are improved evidently compared with pure WPU.
