Abstract
Disclosed is a silver nanowire patterning method including patterning an adhesive conductive polymer thin-film on a substrate, fabricating a polydimethylsiloxane (PDMS) stamp coated with a silver nanowire thin-film, and bonding the substrate patterned with the conductive polymer thin-film to the PDMS stamp coated with the silver nanowire thin-film and then separating the two bonded substrates.
Claims19
A silver nanowire patterning method comprising:
- forming a pattern of an adhesive conductive polymer thin-film on a substrate;
- fabricating a polydimethylsiloxane (PDMS) stamp having a bottom surface coated with a silver nanowire thin-film;
- and
- bonding the substrate patterned with the conductive polymer thin-film to the PDMS stamp having the bottom surface coated with the silver nanowire thin-film and then separating the substrate from the PDMS stamp,
- wherein the forming of the pattern comprises printing the pattern of the adhesive conductive polymer thin-film onto the substrate using an inkjet printer, and
- wherein, after separation of the substrate from the PDMS stamp, at least a part of the silver nanowire thin-film is attached to the pattern of the conductive polymer thin-film on the substrate,
- wherein the bottom surface of the PDMS stamp is planar and entirely coated with the silver nanowire thin-film when bonding the substrate to the PDMS stamp.
