摘要： 用反相微乳法成功地合成了蛋白银超微细粒子,并首次研究了蛋白银超微细粒子分散于绝缘油中所形成的电流变液的结构、稳定性、静态屈服应力和漏电流,讨论了影响这些参数的因素.指出蛋白银电流变液在较低的电场下,具有较大的静态屈服应力,其漏电流密度(J)小,且J∝aEb.

Abstract: The synthesis of protein-silver ultrafine particles by inverted microemulsion method and the preparation of ER fluid of these particles dispersing in insulating oil are reported.Several parameters of the ER fluid are studied including the structure,stability,static yield stress (τs) and the leakage cur rent density (J).Factors which affect the above parameters are discussed.The ER fluid of protein-silver shows high yield stress and low leakage current even in weak electric field (E),and J∝aEb.
