| Abstract: | The nanocomposite of PVA-Chitosan with silica was synthesized via a water-in-oil reverse microemulsion method. Thereafter, Transmission electron microscopy, Infrared Spectroscopy, Fluorescence spectrum method etc., were used to characterize the nanocomposites, it was found that the nanoparticles were spherical, monodisperse, and uniform with 80 nm size, the water-soluble and chemical stability were improved because of the PVA was added into silica nanocomposites. |
