| 中文摘要: |
| 对自制的多羟基超支化聚氨酯进行改性,制备了超支化杂化聚氨酯和光固化超支化聚氨酯,采用傅立叶红外光谱和核磁共振氢谱对预期产物进行表征,然后与不同比例的正硅酸乙酯和钛酸正丁酯共混水解,得到一系列光固化超支化有机无机杂化溶胶。用原子力显微镜表征了杂化涂层的表面形貌,并测试了涂层的物理性能。结果表明:杂化涂层的表面质量随无机物含量的增加而变差,SiO2 杂化涂层的表面质量优于TiO2 杂化涂层,其混合杂化涂层的表面质量介于两者之间;杂化涂层的摆杆硬度随着无机物含量的增加而增大,超支化SiO2杂化涂层的性能较好。 |

| The characters of hyperbranched hybrid polyurethane and UV curable hyperbranched polyurethane prepared from the modified home-made polyhydric hyperbranched polyurethane were investigated by fourier transform infrared spectroscopy and 1H nuclear magnetic resonance. Then a series of UV curable organic-inorgnic hybrid sol have been prepared by blending hydrolysis with different proportions tetraethyl orthosilicate and tetrabutyl titanate, and the surface topography of the hybrid coatings were investigated by atomic force microscopy,and the physical properties of the coatings were tested. The results showed that the surface quality of the coatings became worse as the inorgani ccontent increased. The surface quality of SiO2 hybrid coatings was better than TiO2 hybrid coatings, and their mixture hybrid coatings was in between. With the increase of inorganic content the pendulum hardness of the coatings got better. And the properties of hyperbranched SiO2 hybrid coatings was better than others. |
