摘要
利用静电纺丝技术制备聚甲基丙烯酸甲酯(PMMA)/蒙脱土(OMMT)/二氧化钛(TiO_2)复合纳米纤维膜,采用扫描电子显微镜(SEM)观察纳米纤维形态,采用能谱仪(EDX)、傅里叶变换红外光谱(FTIR)等分析手段对样品的表观形态、化学结构进行表征,同时,研究复合纳米纤维膜对亚甲基蓝溶液的光催化降解性能。研究结果表明,用质量为50mg的复合纳米纤维膜作为光催化材料,在500 W汞灯、波长为365nm紫外光照射120min的条件下,对50mL浓度为5.0mg/L亚甲基蓝溶液的分解率达到79.23%,表明复合纳米纤维膜具有较好的光催化效果。
The polymethylmethacrylate （PMMA）/montmorillonoid （OMMT）/titanium dioxide （TiO2） composite nanofibrous membrane was obtained by electrospinning technique. The morphology of the nanofibers was observed by scanning electron microscope （SEM）, and the samples were characterized by means of energy dispersive spectroscopy （EDX） and Fourier transform infrared spectroscopy （FTIR）. At the same time, the photocatalytic degradation of methylene blue solution was also investigated by the use of the composite nanofibrous membrane. The results show that the decomposition rate of methylene blue solution （50 mL, 5.0 mg/L） is 79.23% with composite nanofibrous membrane at the mass of 50 mg as photocatalytic materials, under the wavelength of 365 nm UV light （500 W mercury lamp） for 120 min, Which shows that composite nanofibrous membrane exhibits excellent photocatalytic property.
