Abstract
In spite of the channel length change, flow rates of microchannels were practically same at the same electric field. But microchannels, of which PDMS surface contact angles were 20° and 80°, showed different flow rates at the same electric field. Such flow rate difference was explained by relative zeta potential to show the effect of surface hydrophilicity change. This result showed that surface contact angle change affects the flow rate change of fluid in microchannel.
