基于天然橡胶聚合物（NR-胶乳）的磁响应流体涉及磁性复合流体（MCF）橡胶液体。对于广泛的工程应用的悬浮液或液体的颗粒，其电气特性的流体悬浮液进行了研究，以获得有用的结果，可能是重要的，在器件的研究，如流体传感器和电容器。本文提出将MCF与胶乳复配，可制得MCF胶液。通过测量外加电压下的电性能，研究了磁性颗粒和橡胶分子的聚集对磁场下电性能的影响。根据颗粒聚集的条件，电气特性以线性或非线性响应变化。电荷的容量也随着颗粒聚集的条件而变化。这些结果表明，MCF橡胶液是一种新型的混合电容器。
Magnetically responsive fluid based on polymers of natural rubber (NR-latex) involves a magnetic compound fluid (MCF) rubber liquid. For a wide range of engineering applications of suspensions or liquids with particles, their electrical characteristics of fluidic suspensions are investigated to obtain useful results that might be important in the study of devices, such as fluidic sensors and capacitors. The author of the present paper proposes that MCF rubber liquid can be produced by combining MCF and rubber latex. The influence of the aggregation of magnetic particles and rubber molecules on electrical characteristics under a magnetic field was investigated by measuring electrical properties under an applied voltage. The electrical characteristics change with a linear or a nonlinear response, based on conditions of particle aggregation. The capacity of the electric charge also changes with the conditions of particle aggregation. These results show that MCF rubber liquid is a novel hybrid capacitor.
