【Abstract】 As a kind of novel material, the microsphere is used extensively in normal industry such as plastic, paint, biology, microelectronics and drug transport, and because of the special optical and structure characteristic the silica composite microspheres is reports in many study. In this study the composite silica microspheres was obtained through the polymerization of urea and formaldehyde occurred in the silica sol that prepared from the hydrolyzation of tetraethyl orthosilicate. The result of the characterization show that the composite silica microspheres synthesized in different condition has varies Morphologies. The different in Morphology is cause by the different way of the Polymerization in silica sol.更多还原
