PURPOSE:To obtain the title fluid which generates large shear stress and is excellent in current characteristics and stability by mixing a dispersed phase comprising dielectric particles with a dispersion medium comprising an insulated liquid and an additive comprising a complex of a specified composition. CONSTITUTION:A composite is prepared by compositing particles insoluble in the below-mentioned insulating liquid with a polysiloxane-containing polymer comprising polysiloxane-containing structural units of formula I wherein A is -COO- or phenylene; R<1> is H or methyl; R<2> is 1-6C alkylene; and R<3> to R<13> are each aryl, 1-6C alkyl, etc., and structural units containing a dispersed-phase- adsorbing chain and selected from formulas II, III and IV wherein B and E are each -COO- or phenylene; R<14>, R<17> and R<19> are each H or methyl; R<15> is 2-4C alkylene; R<16> and R<19> are each hydrogen or alkyl; R<20> is 6-30C alkyl; and D is formula V, formula VI or -CN, etc. This composite is mixed with a dispersed phase comprising dielectric particles and a dispersion medium comprising an insulating liquid. |
