摘　　要：以硝酸锌、六亚甲基四胺为原料,通过低温水浴方法在芳纶Ⅲ表面实现氧化锌纳米棒的修饰。采用X射线衍射仪、扫描电子显微镜、能量色散X射线谱仪、紫外分光光度计和热失重仪等测试手段对所制备的样品进行了表征。结果表明,芳纶Ⅲ表面生长的氧化锌纳米棒为六方纤锌矿相结构,并且择优取向生长。借助于氧化锌纳米棒吸收紫外线的能力和耐高温的特性,氧化锌纳米棒修饰后的芳纶Ⅲ具有良好的抗紫外性和优异的热稳定性。ZnO nanorods were fabricated on the surface of aramid fiber Ⅲ using zinc nitrate and hexamethylenetet- ramine though low-temperature hydrothermal process. The structure and morphology of as-prepared samples were charac- terized by SEM,XRD,EDS, UV-siv and TOA. The analysis results showed that ZnO nanorods perpendicularly grown on the fibers were the wurtzite crystal phase, which grew along its preferred direction. The treated aramid fibers Ⅲ had a good ultraviolet resistance and excellent heat resistance with the merits of ZnO nanocrystal in ability of absorption ultraviolet light and high temperature characteristic.
