Sumario:Mullite nanowhiskers are prepared by a facile technique at low temperature using mica and AlF(3) as raw material. Mica acts as reactant as well as substrate. By controlling the reaction temperature and holding time, the mullite nanowhisker array with uniform morphology is obtained. The nanowhisker array possesses Al-rich single crystalline with an average of 80 nm in diameter and 20 μm in length. After decorated with Au nanoparticles, the array exhibits high surface enhanced Raman scattering (SERS) activity with an SERS enhancement factor (EF) of 1.35 × 10(9). It also remains good SERS signal detection with a relative standard deviation of 7.33% under corrosion condition.
