This paper demonstrates a new micro-patterning method for fabricating electrodes from a conductive polyaniline (PANI)/MWNT composite using an optically-induced electrokinetics (OEK) chip. This method quickly patterns flexible polymeric electrodes with different geometries when a square waveform signal with amplitudes from 16-20 Volts and frequencies from 20-30 kHz are applied. The geometric dimensions of the electrodes can be varied dynamically by controlling the size and exposure time of the light pattern. The surface morphology of electrodes patterned by this method is scanned by an atomic force microscope (AFM) and a scanning electron microscope (SEM) which show that the electrodes are uniform and continuous. Furthermore, the geometric dimensions and resistances of the electrodes are measured and analyzed. Experimental results reveal that the relationship between the resistance and geometries of the electrodes obey Ohm's law and the resistivity of the electrodes is about 0.03 Omega.m.   Controllable Assembly of SWCNTs Using Dielectrophoresis in a Microchannel 会议论文 2012 International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO), Xi, August 29 - September1, 2012 作者:  Yu HB(于海波);  Dong ZL(董再励);  John Mai;  Li WJ(李文荣);  S.
