Study on the influence of high resolutionmicroinjection technique on printing surface micro pattern

高效制备表面微图案是新型表面微观化材料制备的重要过程,其工艺流程一直被优化和探寻。介绍了一种低成本高效率的在玻璃表面上制备微图案的方法。通过微喷技术使用功能性墨水,在玻璃表面打印出高分辨率的微米级图案。观察微图案的微观形貌来评估打印质量,同时对影响打印质量的不同工艺参数(喷孔个数、压电波形、点间距)进行研究。实验结果表明,用型号TEST-01的打印墨水在玻璃表面打印时,设定压电波形为TEST-01、喷孔数为2、DS值为20μm可得到最佳的打印效果。

Efficient preparation of surface micropatterns is an important process in the preparation of new surface microcosmic materials,and its technological process has been optimized and explored.A low cost and high efficiency method for preparing micropatterns on glass surface is introduced.Using functional ink,high resolution micron patterns are printed on the glass surface by microinjection technology.The micro-morphology of the micro-pattern was observed to evaluate the print quality,and the different process parameters(the number of orifices,the piezoelectric waveform and the point spacing)that affect the print quality were also studied.The experimental results show that when the print ink with the model TEST-01 is printed on the surface of the glass,the piezoelectric waveform is set to TEST-01,the number of injection holes is 2,and the value of DS is 20μm,and the best printing effect can be obtained.
