Abstract: 본 발명은 수용성 전분을 전도성 입자로 함유하는 전기변성유체에 있어서, 상기 전기변성 유체의 수분 함량이 5 중량% 미만인 전기변성유체를 제공한다. 이러한 전기변성유체는 전도성 입자인 수용성 전분을 비전도성 용매 중에 분산시킴으로써 전기장 무부하 시에는 뉴토니안 유체(Newtonian Fluids)의 특성을 나타내지만, 전기장 부하시 전기장의 증가에 따라 항복응력과 가점성이 증가하여 유동을 제어할 수 있는 특성을 보인다.
이러한 특성은 현가장치, 제진대, 엔진 마운트 등의 제어가 가능한 가변감쇠기구나 브레이크, 클러치 등의 동력장치에 응용이 가능하며, 자동차 및 항공산업 등을 비롯한 많은 분야에서 적용이 가능하다.-
