将纳米MnO2催化剂粉末负载到自制的含活性炭的腈氯纶纤维上,在室温下对甲醛进行吸附分解研究。借助扫描电子显微镜(SEM)进行显微结构观察,并分析了不同处理情况的负载纤维对甲醛的去除率。结果表明,研磨6h的MnO2粉末分散均匀,平均粒径可达300 nm,以平铺的形式均匀地负载于纤维上;研磨6h的MnO2粉末反应72h对甲醛的去除率达94.07%;二甲基甲酰胺(DMF)处理后的纤维对甲醛的去除率有所提高。
The acrylonitrile-vinylidene chloride(AN-VDC) copolymer fiber containing actived carbon(AC) loaded nano-MnO2 had been made in the laboratory.The fiber was applied to adsorb and decompose formaldehyde at room temperature.The micro-structure of AC/P(AN-VDC)F-MnO2 was investigated by scanning electron microscope(SEM) and the removal efficiency of formaldehyde of AC/P(AN-VDC)F-MnO2 after treated were analyzed.The experimental result shows that,the MnO2 microparticles scatter uniformally after grinded for 6h,the average diameter is 300nm approximately,loading on the surface of fiber in flat successfully.The removal efficiency of formaldehyde of MnO2 grinded for 6h is up to 94.07% after 72h,and it increases after treated with N,N-dimethyl formamide(DMF).
