Název v původním jazyce
Covalent Modification Of Carbonyl Iron Microparticles With Polybutylacrylate Shell And Behaviour Of Their Suspensions In Magnetic Field
Popis výsledku v původním jazyce
Magnetorheological (MR) suspensions are generally two-phase systems consisting of magnetic particles and silicone oil. Upon application of an external magnetic field particles become magnetized and form chain-like structures, resulting in the change of the rheological behaviour of whole suspension. Viscosity can increase in several orders of magnitude and then return to its original value when magnetic field is replaced. Thus, the viscosity of such suspensions can be controlled using various magnetic field strengths. Reversible change of viscosity can find application in damping systems or torque transducers. However, there are still some drawbacks related to sedimentation stability of suspensions and oxidation stability of particles. Therefore, this contribution is aimed on the covalent modification of the carbonyl iron particles with poly(n-butyl acrylate) using atom transfer radical polymerization (ATRP) in order to enhance the overall stability of the carbonyl iron particles after
