The Surface Modification of Magnetic Particles with Polyamidoamine Dendron

Popis výsledku v původním jazyce

Magnetorheological elastomers are important kind of intelligent systems that can alter their properties upon an application of an external magnetic field. Crucial for their performance is interaction between polymer matrix and magnetic filler, thus, it is necessary to control the compatibility between the matrix and magnetic particles. In this study, polyamidoamine dendron was successfully introduced onto surface of carbonyl iron particles using divergent approach in order to provide novel magnetic particles for magnetorheological elastomers. The presence of a thin layer of polyamidoamine dendron on the carbonyl iron particles was confirmed by energy dispersive X-ray, infrared spectroscopy and transmission electron microscopy, which confirmed a thin layer in nanometers formed on the surface of the particles. The coated carbonyl iron particles exhibited superior chemical stability when compared to non-coated ones, while the saturation magnetization decreased only negligibly from 207.0 emu g–1 to 203.5 emu g–1 for pure carbonyl iron particles and polyamidoamine dendron-coated carbonyl iron particles, respectively.
