Název v původním jazyce
A tensiometric study of magnetorheological suspensions' stability
Popis výsledku v původním jazyce
A thin (3-aminopropyl)triethoxysilane (3APTS) layer with a grafting density around 50 groups per nm2 was coated onto soft magnetic carbonyl iron (CI) particles. Their physical characteristics were examined using various methods, and the results revealedthat the coating layer did not affect the particles' morphology and magnetic properties while their resistance against thermal oxidation and chemical degradation was considerably improved. This study further evaluates the surface free energy of the particles under investigation using tensiometry, namely capillary rise experimental methods based on the Washburn theory. The dispersive and polar components of surface free energy were subsequently computed through the application of the Owens?Wendt?Rabel?Kaeble theory. It was observed that the coating of CI particles with 3APTS increased the dispersive component of surface free energy, resulting in the improved compatibility of such particles with non-polar silicone oil which is used as a c
