Synthesis and characterization of magnetic nanoparticles modified by 3-aminopropyltriethoxy-silane
摘要
Abstract
Superparamagnetic Fe304 nanoparticles were first synthesized by hydrothermal coprecipitation of ferric and ferrous ions, followed by the modification of their surfaces with 3-aminopropyhriethoxy-silane (APTES). The structure and properties of as-synthesized nanoparticles were characterized by FTIR,TEM,TGA,and vibrating sample magnetometer (VSM). The results indicate that nanoparticles are coated successfully by APTES. The coat- ing layer gradually becomes complete and thicker with the addition of APTES. It also shows that the magnetic properties of magnetic nanocomposites are enhanced with the addition of APTES within certain degree. Beyond this, the magnetic performance decreases.关键词
