| Research Abstract |
We found that track etched membrane made of poly carbonate with pores of 400 nm coated with gold using magnetron spattering become excellent electrophoresis pomp under applying DC voltage. If an alternating voltage is imposed to the track etched membrane coated with gold in water, alternating flowof water was rectified and the membrane acted as alternating voltage driven DC electro osmotic pomp. It is considered that difference of zeta potentials on the both side of the membrane generated rectification property. Furthermore, we prepared ratchet membrane by fixing nanobeads on one side using ultrahigh molecular weight polymer spacers. These results are expected to be applied to disposable electro-osmotic pump that does not cause pH changes and the generation of gases by electrolysis of water.
