用丝网印刷技术制备薄膜微电极的方法研究

对丝网印刷术在微电极制备方面的应用作了系统和详尽的描述，对绷网、制阳图底板、涂布感光胶、晒网、显影、坚膜、印刷等印制各步骤中所需注意事项和技巧作了总结。考察了标记方式、曝光时间、显影时间等的影响，并在优化条件下制成了微电极。用1mmol／L铁氰化钾在微电极上进行循环伏安扫描实验。结果表明，所制得的微电极条具有良好的电化学性能。用此方法可大批量制得廉价的适用于电化学研究和应用的微电极条。

Preparation of Micro-electrode by Screen-printed Technology

The methods for the preparation of screen-printed micro-electrode (SPME) were reported in detail. Technique of stretching the net tight, plate making, gelatinizing, exposal, develop, second exposal was summarized. The effects, such as calibration based on several tag types, exposal and develop time and thichness of plate basedon different develop time, were studied. Lots of SPMEs were made on optimal condition. Cyclic voltammetric response of the SPME was detected in 0.1 mmol/L K_3Fe(CN)_6. The result of experiment indicats that prepared screen-printed micro-electrode has excellent electrochemistry performance. Lots of cheaper micro-electrodes can be produced by the technology.
