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 solution to 20% silica solution, random nanofibrous silica membrane were produced after being subject to pyrolysis at 800°C for 2 hours. The mean diameter of the silica nanofibres was 256 nm. With a solution of 50% PEO to 50% silica solution, three-dimensional wool-like network of nanofibres was achieved.
