| titleOfInvention | Powder and electroviscous fluid |
| abstract | PURPOSE:To obtain powder consisting of complex particles in which electrically insulating fine particles are unevenly dispersed in a matrix phase having a specific electric conductivity in a state rich in the surface side and poor in the center side, and capable of exhibiting a high level electroviscous effect in wide temperature range for a long period. CONSTITUTION:Globes of phenol which is a thermosetting resin are impregnated with an ester orthosilicate for a whole day and night, and filtered and washed with ethanol and heated in distilled water containing toluenesulfonic acid at 40 deg.C for 8hr and dried. Then the globes are carbonized by heating at 600 deg.C for 1hr in an argon atmosphere to provide the powder consisting of complex particles 1 in which fine particles 3 are unevenly dispersed in a matrix phase 2 in a state rich in the surface side and poor in the center side or in a state poor in the surface side and rich in the center side. The matrix phase 2 has 10<-10> to 10<2>Scm<-1> electric conductivity and contains these dispersed fine particles 3 consisting of one or more kinds of materials of semiconductor, insulator, etc., whose electric conductivities are <=1/10 of that of the matrix phase and whose dispersing amount in the complex particles 1 is <=40wt.%. |
