| 摘 要： | 采用均相沉淀法在碳纤维表面进行了NiO涂覆，研究了沉淀剂种类、脱水方式、沉淀剂浓度、沉淀剂添加速度和沉积反应时间对涂覆效果的影响. 采用SEM和XRD对涂层进行了表征，得到了制备NiO涂层较为合适的工艺条件为：以尿素为沉淀剂，采取缓慢升温的方式脱水，沉淀剂浓度0.20 mol/L，沉淀剂滴加速度2 mL/min，反应时间120 min. 在此条件下制备的NiO涂层厚度均匀，无脱落现象. 抗氧化性测试结果表明，涂覆NiO涂层后，碳纤维的抗氧化性有明显的提高.

| Abstract: | NiO was deposited on carbon fibers by homogeneous precipitation method. The influences of precipitation agents, dehydration method, precipitator concentration, addition speed of precipitator and deposition time on depositing were examined. NiO coating was characterized by SEM and XRD. Proper process conditions of NiO depositing on carbon fibers were obtained as follows: urea as the precipitator, Ni(OH)2 dehydrated by slow heating method, the precipitator concentration at 0.20 mol/L, addition speed of precip... |
