Description
  • Byla připravena mezoporézní silika (SBA-15) s různým obsahem zapouzdřeného polypyrolu (PPy) v kanálcích. Analýza pomocí XRD a absorpčních/desorpčních izoterem N2 ukazuje, že různý obsah PPy v kanálcích neovlivňuje uspořádanou hexagonální strukturu výsledného nanokompozitu PPy/SBA-15. Dále byly zkoumány elektroreologické (ER) vlastnosti nanokompozitů s různým obsahem PPy v ustáleném a oscilačním smykovém poli. Výsledky ukazují, že kapaliny s dispergovaným PPy/SBA-15 vykazují v elektrickém poli typické ER a viskoelastické chování. ER efekt závisí především na obsahu PPy, přičemž existuje optimální obsah PPy, při němž je ER efekt nejvyšší. (cs)
  • Encapsulated polypyrrole (PPy) with different amount in the channels of mesoporous silica (SBA-15) was synthesized. The XRD and N2 adsorption/desorption isotherms analysis show that PPy with different loadings in the channels does not affect the ordered hexagonal structure of resultant PPy/SBA-15 nanocomposites. Further, the electrorheological (ER) properties of the nanocomposites with different PPy loadings were investigated by steady and oscillatory shear experiments. The results reveal that PPy/SBA-15 fluids exhibit typical ER and viscoelastic behavior under the applied electric field. ER response depends mainly on PPy loadings and there is an optimum PPy loading for strong ER effect.
