In general, the characteristic of alumina is hard, hard-wearing, high melting point and very stable. The polymer is high plastic, so we can mix with alumina and polymer to develop the new characteristic material. 　The Research uses sol-gel to control hydrolsis and condensation reactions of the silane coupling agent. The way can make nano-alumina powder coated with self assembled silane layers. The nano-alumina powder coated with silane layers can be a filler of polymers. The research uses FTIR(Fourier Transform Infrared Spectroscopy) and SNMR(Solid Nuclear Magnetic Resonance Spectroscopy) to determine powder surface that had be coverd with silane layers. Finally, using TEM(Transmission Electron Microscope) proves the core-shell structuce nano-alumina powder coated with the silane layers.
