I feel like he's fishing for publicity. All he really is doing is another way to make paper conductive, but carbon paper has been around forever.

- aarongough 17y agoHe's not simply making paper conductive. Something that is solely conductive cannot store a charge. What he's doing is using a specially formulated ink to turn the paper into a capacitor, which is far more novel than simply making paper conductive.
- thefool 17y agoI don't think so, from his abstract: "Here, we show that commercially available paper can be made highly conductive with a sheet resistance as low as 1 ohm per square (Ω/sq) by using simple solution processes to achieve conformal coating of single-walled carbon nanotube (CNT) and silver nanowire films. Compared with plastics, paper substrates can dramatically improve film adhesion, greatly simplify the coating process, and significantly lower the cost." - http://www.pnas.org/content/early/2009/12/04/0908858106 http://www.pnas.org/content/early/2009/12/04/0908858106 From what I understand, he is using the fact that the nano-tube (ink) layer is conductive and the fact that paper acts as a good insulator to assume that he can use this to craft a better capacitor. Unless that "1 ohm per square" (something) is an incredibly low resistance, then I fail to see what is so incredibly novel.
- aarongough 17y agoRe-reading the article: you are actually correct. He really is just working on thin-film conductors. From my first reading of the article I was under the impression that he was producing and entire capacitive device simply using a printing process.
