摘要:
为获得性能优异的超疏水光催化材料,通过浸泡和喷涂的方法合成了一种超疏水海绵,将聚二甲基硅氧烷 (PDMS) 与四氧化三铁(Fe3O4)颗粒、二氧化钛(TiO2 , P25)颗粒分别在乙酸乙酯(EtOAc)中光接枝,然后负载于海绵上,获得超疏水P25@Fe3O4@PDMS海绵,实现了对含油废水的高效分离和对染料的高效降解。使用接触角仪、傅里叶变换红外光谱仪、扫描电子显微镜对其进行表征,探究了 PDMS、EtOAc、Fe3O4@PDMS、P25@PDMS的比例对其超疏水性能的影响,对其油水、乳液分离性能进行了测试。结果表明:超疏水P25@Fe3O4@PDMS海绵对二氯甲烷、氯仿和四氯化碳3种重油分离效率高达98.6 % 以上,对有机溶剂的吸附量在21.3~56.9 g/g 之间,24 h吸附了几乎所有乳化油。此外,超疏水海绵对尼罗红还具有一定的光降解能力。该超疏水P25@Fe3O4@PDMS海绵具有良好的机械稳定性和化学稳定性,经过100次摩擦,水接触角仍大于150°,在酸、碱、盐和高温条件下,依然能够保持优异的超疏水性能。该超疏水海绵原料对环境无害、价格便宜且易于大量获取,具有良好的应用前景。
Abstract:
To obtain a superhydrophobic photocatalytic material with excellent performance, a superhydrophobic sponge was synthesized using immersion and spraying methods. Polydimethylsiloxane (PDMS) was photografted with ferric tetraoxide (Fe3O4) particles and titanium dioxide (TiO2,P25) particles in ethyl acetate EtOAc, and then loaded onto the sponge to create a superhydrophobic P25@Fe3O4@PDMS sponge, which demonstrated efficient separation of oily wastewater and efficient degradation of dyes. It was characterized using a contact angle meter, Fourier transform infrared spectroscopy, and scanning electron microscopy, and the effect of the ratio of PDMS, EtOAc, Fe3O4@PDMS and P25@PDMS on its superhydrophobic properties was explored, and its oil-water and emulsion separation properties were tested. The results showed that the superhydrophobic P25@Fe3O4@PDMS sponge has a separation efficiency of more than 98.6% for three heavy oils: dichloromethane, chloroform and carbon tetrachloride. The adsorption capacity of organic solvents ranged from 21.3 to 56.9 g/g, and almost all emulsified oils were adsorbed in 24 hours. In addition, the superhydrophobic sponge has a certain photodegradation ability for Nile red. The superhydrophobic P25@Fe3O4@PDMS sponge has good mechanical and chemical stability. After 100 times of friction, the water contact angle was still greater than 150°. It can maintain excellent superhydrophobic properties under acidic, alkaline, saltine and high-temperature conditions. The raw materials for the superhydrophobic sponge are environmentally friendly, inexpensive and easily accessible in large quantities, so it has good application prospects.
