せん断・圧縮法によって調製したFe₃O₄/siO₂二重層被覆型複合粒子における層間相互作用のXPSによる解析

抄録

Composite microspheres of polystyrene or silica coated with a double layer of Fe₃O₄/SiO₂ were prepared via mechanical routes using a shear-compressing type machine. The binding energy of Fe_2p3/2 measured by XPS increased, while that of Si_2p decreased after composite formation. These synchronized shifts increased with increasing intensity of mechnical treatment. After heat treatment, chemical interaction at the interlayer Fe₃O₄/SiO₂ interface in a composite particle during mechanical treatment was verified. The fine structure of the interlayer boundary was also examined in detail by electron microscopy.
