Abstract

Hybrid organic-inorganic nanocomposite silica with surfactant � cetylpyridinium chloride with the polyphase structure, having a high electrorheological activity, is synthesized using sol-gel method. Physical-mechanical characteristics of dispersions based on mineral oil and synthesized powder with the concentration of 20 and 30 % by weight are investigated. The results of the shear stress measurements versus the strength of the dc and ac (frequency 50 Hz) electric fields (0 � 3.5 kV/mm) at Couette shear (shear rate 8 � 390 s) and yield stress in the range of temperatures 20 � 97 �C are presented. The comparative analysis of the results obtained with the results for the powder of the hybrid organic-inorganic nanocomposite silica/ polyethylene glycol is carried out.
