ELECTROSPINNING OF 2D AND 3D SILICA NANOFIBRES FROM A COLLOIDAL SOLUTION

Silica nanofibres were synthesised by electrospinning a commercially available silica solution with an aqueous 5% poly(ethylene oxide) (PEO) solution to produce composite PEO/silica nanofibres. Using a ratio of 80% PEO to 20% silica, a random nanofibrous silica membrane was produced after being subj...

Summary:Silica nanofibres were synthesised by electrospinning a commercially available silica solution with an aqueous 5% poly(ethylene oxide) (PEO) solution to produce composite PEO/silica nanofibres. Using a ratio of 80% PEO to 20% silica, a random nanofibrous silica membrane was produced after being subject to pyrolysis at 800 C for 2 h. The mean diameter of the silica nanofibres was 256 nm. With a ratio of 50% PEO to 50% silica, a three-dimensional wool-like network of nanofibres was obtained.
