PRODUCING METHOD OF NANO ELECTRO RHEOLOGICAL FLUID WITH THE IMPROVED DISPERSION STABILITY AND REDISPERSIBILITY, USING A POLY(3,4-ETHYLENEDIOXYTHIOPHENE) NANOTUBE

摘要

PURPOSE: A producing method of nano electro rheological fluid is provided to use an oil-soluble surfactant to improve the dispersion stability of the nano electro rheological fluid, and to secure the electro-rheological property of the fluid by the content of nanoparticles.;CONSTITUTION: A producing method of nano electro rheological fluid comprises the following steps: controlling the electrical property of a poly(3,4-ethylenedioxythiophene) nanotube by dedoping; forming the nano electro rheological fluid by dispersing the dedoped poly(3,4-ethylenedioxythiophene) nanotube an oil-soluble surfactant to silicon fluid; considering the electro-rheological property of the nano electro rheological fluid using a rheometer connected with a DC power supply; and considering the dispersion stability of the nano electro rheological fluid by calculating the sedimentation rate by the time.;COPYRIGHT KIPO 2010
