PROCESS FOR MAKING MATERIALS WITH MICRO-OR NANOSTRUCTURED CONDUCTIVE LAYERS

摘要

Disclosed are methods for making conductive materials. The methods can be used to make transparent, opaque, or reflective electrodes by using the same materials and equipment but varying the processing conditions or amounts of materials used. The methods can include: (a) providing a substrate comprising a first surface and an opposite second surface, wherein micro- or nanostructures are disposed on at least a portion of the first surface, and wherein the first surface is not pre-conditioned to increase attachment between the micro- or nanostructures and the substrate; (b) applying heat to heat the substrate surface to a temperature that is greater than the glass transition temperature or the Vicat softening temperature of the substrate and less than the melting point of the substrate; (c) applying pressure such that the substrate and the micro- or nanostructures are pressed together; and (d) removing the pressure to obtain the conductive material.
