  Abstract

We report a simple and versatile method to prepare hydrophobic composite SiO2 membrane. The electrospun SiO2 membrane was selected due to its good flexibility and thermal stability. The hydrophobic SiO2 membrane was succussfully prepared by simply evaporating a thin polydimethylsiloxane (PDMS) layer on the fiber surface. The characterization results show that the PDMS layer is too thin to be observed. The PDMS coating has no influence on the porous structure of the fibrous membrane, but imparts the good hydrophobicity and oleophilicity to the SiO2 nanofibers. As demonstration, the hydrophobic SiO2-PDMS membrane displays good oil absorption performance from the oil/water mixture, as well as filtration membrane for oil/water separation. Additionally, due to the proper pore size and hydrophobic surface, the SiO2-PDMS membrane shows good waterproof performance and breathability at the same time.
