Description
  • Polymerní kompozity plněné měkkými ferrity nabízí široké možnosti pro jejich aplikace v různých elektronických zařízení v důsledku specifického frekvenčního chování komplexní permeability. Existuje způsob jak zlepšit hodnotu permeability magnetických polymerních kompozitů. Navrhli jsme kombinovat ferity s vodivými komponenty v hybridních kompozitech dvěma způsoby. První je přidávání vodivého plniva do polymerní matrice s ferity. Druhý představuje in-situ polymeraci anilínu nebo polypyrolu na povrchu feritových částic za různých polymeračních podmínek. V současnosti vodivá mezifáze mezi feritovými částicemi, které mění hraniční podmínky pro elektromagnetické pole je faktorem, který ovlivňuje magnetické vlastnosti hybridních kompozitů. Sledované změny v magnetických vlastnostech hybridních kompozitů prokázaly zvýšení a posun rezonanční frekvence. (cs)
  • Soft ferrites-filled polymeric composites offer wide possibilities for their application in different electronic devices owing to the specific frequency behavior of their complex permeability. There is a way how to improve permeability value of magnetic polymeric composites. We proposed to combine the ferrite with conductive component in hybrid composites by two different ways. The first is to add conductive filler into the polymer matrix with ferrites. The second constitute in-situ polymerization of aniline or polypyrrole on the surface of ferrite particles under various polymerization conditions. The presents of conducting interface between the ferrite particles, which change the boundary conditions for the electromagnetic field is a factor that influence on the magnetic properties of the hybrid composites. The observed changes in the magnetic properties of the hybrid composites manifest itself in the enhancement? and in shifting of resonance frequency.
