Abstract: A method for forming thin film conductors is disclosed. A thin film precursor material is initially deposited onto a porous substrate. The thin film precursor material is then irradiated with a light pulse in order to transform the thin film precursor material to a thin film such that the thin film is more electrically conductive than the thin film precursor material. Finally, compressive stress is applied to the thin film and the porous substrate to further increase the thin film's electrical conductivity.

A surface treatment solution is applied to the raw base paper and comprises a surface sizing agent and 3 wt % to 15 wt % calcium carbonate.

Abstract: A polymer-based pattern mask system and methods of masking and patterning a substrate employ an organosilane to enhance adhesion between a pattern mask and the substrate. The substrate is compatible with the organosilane. The methods include applying a coating of the organosilane to a substrate surface and printing a pattern mask on the coated surface using a roll-to-roll printing process. The pattern mask is polymer-based. The organosilane enhances adhesion during printing of the pattern mask. The method of patterning further includes patterning the substrate surface and lifting-off the pattern mask. The organosilane further enhances adhesion during patterning and does not hinder lifting-off the pattern mask. The system includes the pattern mask, the organosilane and a lift-off agent to remove the pattern mask.
