摘要：

Electrospun nanofiber mats were prepared from low-viscosity sol-gel silica without the addition of a carrier polymer. Silica sols synthesized from tetraethyl orthosilicate (TEOS) under acidic conditions were electrospun into nanofibers in the viscosity range of 2 to 4 mPa.s. The influence of ethanol and water concentrations on the viscosity of as-synthesized and aged silica sols was also determined. Nanofibers produced from as-synthesized sols with a TEOS:H2O ratio of 1:2 ranged in diameter from 50 nm to 200 nm. Increases in viscosity, whether due to aging or increased water concentration in the sol resulted in fragmented nanofibers. Nanofiber mats used as the stationary phase for thin layer chromatography (TLC) were able to separate components of a test dye mixture.
