The development of the namo-technology material science have been to microstructure. How to make excellent organic-inorganic compound material is the researching focus. Organic-Inorganic compound material have the unique structure and component,which let it have good capability of photics, electricity, biological iatrology, magnetics and all the different components have co-operating effect,the effect will be change if the components is different, so how to make he undefiled and functionality rganic-inorganic compound material is challenge topicThe experiment takes the preparation of Nucleus-Shell compound Micro-spheres as the subject investigated and studying the effect of various factors of emulsion polymerization and sol-gel manner.at last we make use of improving Emulsifier-free emulsion Polymerization and so-gel manner to prepare monodispersity PS Micro-spheres,the SiO2 of altering character Micro-spheres and organic(PS)-inorganic (SiO2)compound Micro-spheres,this works make the designing and preparing for organic-inorganic heterozygosity Micro-spheres to be possible, the form of structure,surface features and structure of the Micro-spheres was tested under TEM,FT-IR and ESEM.This paper discuss effect of different reaction condition to PS Micro-spheres size,surfacial feature and conformation,at last the plan of the experiment was confirmed, this work provide a route of preparing organic(PS)-inorganic (SiO2)compound Micro-spheres...
