English
Synthesis and Modification of Superparamagnetic Nanocompositions(Fe3O4/PVA)/SiO2
Abstract:
Nanocompositions(Fe3O4/PVA)/SiO2 have been prepared by three-step method(co-precipitation,miniemulsion polymerization,Stöber process) and structurally characterized by TEM.According to the image of Fe3O4/PVA/SiO2 by TEM,the morphology is obviously core-shell structure: the average diameter of Fe3O4/PVAc is 100 nm;the diameter of(Fe3O4/PVA)/SiO2 is controllable within a certain range(100~500 nm).And(Fe3O4/PVA)/SiO2-glutaraldehyde can capture BSA within a certain time at a certain tempe-rature.
