Modification of the carbonyl iron particles using SI-ATRP approach with poly(2-(1H-pyrrole-1-Yl)ethyl methacrylate

Popis výsledku v původním jazyce

This study is focused on the synthesis of core-shell type of magnetic particles, where magnetic core is carbonyl iron (CI) microparticles and conducting shell is poly(2-(1H-pyrrole-1-yl)ethyl methacrylate) (PPEMA) synthesized using atom transfer radical polymerization (ATRP) technique. In order to obtain core-shell particles the surface-initiated (SI)-ATRP is used, where both benefits, magnetic behaviour of core and conducting behaviour of shell, are advantages for their intended application as materials for electromagnetic shielding of piezo-resistors. Basic characterizations of the neat CI and CI-PPEMA particles such as magnetization saturation using and conductivity using dielectric spectroscopy are performed. Also the confirmation of the controllable coating using gel permeation chromatography and nuclear magnetic resonance are provided. The successful modification of CI with PPEMA is investigated using Fourier transform infrared spectroscopy. It is also proved by dielectric spectroscopy if such CI-PPEMA particles possess enhanced properties in comparison to neat CI particles and thus should exhibit the improved capability in electromagnetic shielding.
