In this work, an effective strategy on the preparation of the superhydrophobic electrospun nanoparticles (NPs)/polyvinylidene fluoride (PVDF) composite membranes for oil-water separation was developed. The nanofibrous SiO 2 NPs, TiO 2 NPs, and Fe 3 O 4 NPs/PVDF composite membranes were firstly prepared by the electrospinning technique and then immersed into the trimethoxy (1H,1H,2H,2H-heptadecafluorodecyl) silane (TMHFDS) solution to achieve the superhydrophobicity. Furthermore, the electrospun NPs/PVDF composite membranes after the TMHFDS surface modification were investigated by the Fourier-transform infrared (FTIR), the Wide-angle x-ray diffraction (WAXD), the scanning electron microscope (SEM), the two-dimension element mapping as well as the vibrating sample magnetometer (VSM), and their supehydrophobicities were confirmed by the water contact angle measurement. More importantly, the resultant superhydrophobic electrospun NPs/PVDF comp...

一种制备油水分离超疏水电纺纳米粒子/ PVDF复合膜的有效策略

在这项工作中，开发了一种制备用于油水分离的超疏水电纺纳米颗粒（NPs）/聚偏二氟乙烯（PVDF）复合膜的有效策略。首先通过静电纺丝技术制备了纳米纤维SiO 2 NPs，TiO 2 NPs和Fe 3 O 4 NPs / PVDF复合膜，然后将其浸入三甲氧基（1H，1H，2H，2H-十七碳氟癸基）硅烷（TMHFDS）溶液中。达到超疏水性。此外，通过傅立叶变换红外光谱（FTIR），广角X射线衍射（WAXD），扫描电子显微镜（SEM），二维研究了TMHFDS表面改性后的电纺NPs / PVDF复合膜。元素映射以及振动样本磁力计（VSM），通过水接触角测定确认了它们的超疏水性。更重要的是，所得的超疏水电纺丝NPs / PVDF组成...
