Evaluations of vertical resolution of conductive polymer three-dimensional microstructures photofabricated in transparent polymer sheet

摘要

Conductive polymer three-dimensional microstructures were photofabricated utilizing the two-photon absorption of a sensitizer dye. The resulting three-dimensional structures were excised from the transparent polymer sheet using a micro-manipulator. The processing precisions for the vertical direction of the conductive polymer three-dimensional microstructure obtained in the transparent polymer sheet were evaluated in the present study. As a result, for the configurations of the obtained polypyrrole line deposition, the line height/line width ratios were around 5: 1; this ratio is higher than that of other UV resin works (h: w = 2.4-3: 1) and the cross section distortion is not negligible for maintaining the higher reproducibility of the photofabrication.
