LASER DIODE PATTERNING OF TRANSPARENT CONDUCTIVE FILMS

摘要

Methods of patterning metal nanowire containing transparent conductive films using laser diodes, where the films comprise a radiation absorbing substance, such as an infrared absorbing substance or an ultraviolet absorbing substance. The use of laser diodes can decrease the time and costs associated with patterning transparent conductive films comprising nanowires, such as silver nanowires.

主权项

1. A method for patterning a transparent conductive film comprising:
providing a transparent conductive film comprising a first region exhibiting a first resistivity, the first region comprising a metal nanowire and a radiation absorbing substance; and irradiating the transparent conductive film with a radiation source, wherein, after irradiation of the transparent conductive film, the first region exhibits a second resistivity that is higher than the first resistivity.
