    • The present invention relates to an electrorheological fluid composition comprising a dispersion of a plurality of solid particles in an electrically non-conducting liquid, the improvement comprising using as said solid particles a composition having the general formula:[(M).sup.p (H.sub.2 O).sub.x (OH).sub.y ].sup.q.sub.cd [A].sub.r.sub.d .multidot.B.sub.z .multidot.nH.sub.2 Owherein M is a metal cation or a mixture of metal cations at various ratios; p is the total valence of M and has a value of greater than zero; x is zero or has a value greater than zero, y is zero or has a value greater than zero, with the proviso that only one of x or y can be zero at any given time; q has a value of p minus y with the proviso that q has a value of at least one; c has a value of greater than zero; A is an anion or a mixture of anions at various ratios; r is the total valence of A with the proviso that r has a value of at least one; d has a value of greater than zero with the proviso that (q.times.c) is always equal to (r.times.d); B is an amino acid or a mixture of amino acids; z has a value of from 0.01 to 100; and n is a number from 0 to 15. The ER fluids of the present invention have greatly improved yield stress increasing potential stress transfer characteristics, and good dispersion stability.
    • 本发明涉及包含多个固体颗粒在非导电液体中的分散体的电流变流体组合物,其改进包括使用具有以下通式的组合物作为所述固体颗粒:[(M)p(H 2 O)x (OH)y] qcd [A] rdxBzxnH2O其中M是金属阳离子或各种比例的金属阳离子的混合物; p是M的总价并且具有大于零的值; x为零或具有大于零的值,y为零或具有大于零的值,条件是在任何给定时间x或y中只有一个可以为零; q的值为p减去y,条件是q的值至少为1; c的值大于零; A是不同比例的阴离子或阴离子的混合物; r是A的总价,条件是r的值至少为1; d的值大于零,条件是(qxc)总是等于(rxd); B是氨基酸或氨基酸的混合物; z的值为0.01〜100; n为0〜15的数。本发明的ER流体具有大大提高的屈服应力增加势应力传递特性和良好的分散稳定性。
