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.   Controlled growth and supercapacitive behaviors of CVD carbon nanotube arrays 会议论文 11th IUMRS International Conference in Asia, IUMRS-ICA2010, Qingdao, China, September 25, 2010 - September 28, 2010 作者:  Zhao, Dandan;  Yang, Zhi;  Wei, Hao;  Zhang, Yafei 收藏  |  浏览/下载：4/0  |  提交时间：2017/01/20 Chemical vapor deposition  Amorphous carbon  Amorphous silicon  Capacitors  Carbon nanotubes  Catalysts  Electric current collectors  Electrodes  Graphene  Metallic compounds  Secondary batteries  Semiconducting silicon compounds  Silicon wafers  Sodium  Titanium compounds  Active material  Ambient gas  Carbon nanotube array  Catalyst film  Catalyst particles  Chemical vapor  Controlled growth  Current collector  Electrodeposition technique  Graphene layers  Growth conditions  Growth time  Local environments  Low cost approach  Ni foam  Scan rates  Super capacitor  Supercapacitive behavior  Transitional metal oxide  Vertically aligned CNT arrays
