Development of functional polyimides for printabe electronics

各种含有添加剂的聚酰亚胺的表面浮雕图案化只需光照射即可实现，无需显影过程。积极或消极的色调可以通过添加剂的选择来控制。花纹的形成机理是基于光照区内酸或碱的生成影响聚合物的玻璃化转变。聚酰亚胺的表面润湿性也是通过光照射控制的。这些材料被用作可印刷电子制造的有希望的一步。

Surface relief patterning of various polyimides containing additives was successfully performed by only photoirradiation, without development process. positive or negative tone can be controlled by the selection of the additives. Mechanism of the patten formation is based on the Tg change of the polymer affected by the generation of an acid or a base in the photoirradiated area. Surface wettability of the polyimides was also controlled by photoirradiation. Those materials are used as the promising step for printable electronics fabrication.
