METHODS FOR IMPROVING ELECTRICAL ISOLATION OF PATTERNED TRANSPARENT CONDUCTIVE FILMS

摘要

Claimed methods reduce leakage currents in transparent conductive films comprising conductive nanostructures without substantially impairing the films' optical properties or physical integrity. Imposition of electrical stimuli to separate conductive regions leads to reduced conductivity of the intervening lesser conductive regions.

1. A method comprising:
providing a transparent conductive film comprising:
at least one first region exhibiting a first conductivity,at least one second region exhibiting a second conductivity, the at least one second region not being in direct contact with the at least one first region, andat least one third region contacting the at least one first region and the at least one second region, the at least one third region comprising at least one first conductive nanostructure and exhibiting a third conductivity less than both the first conductivity and the second conductivity; and imposing a first electrical stimulus for a first duration between the at least one first region and the at least one second region, wherein, after imposition of the first electrical stimulus for the first duration, the at least one third region exhibits a fourth conductivity less than the third conductivity.
