UCLA researchers figured out how print organic electronics on CDs and DVDs using Lightscribe.
In the future, the researchers plan to further develop this idea by fabricating electronically active devices. They predict that the simple laser welding technique will serve as an important step toward patterning polymer-based organic electronics on a large scale. The technique could be used to pattern a variety of conducting polymer nanofibers in addition to polyaniline, and these polymers can be printed on many different substrates, including paper. Virtually any pattern can be printed, and the same image can be printed repeatedly on the same film in order to increase the contrast. Without the need for photoresists, masks, or post-processing treatment like many other techniques, the new method offers a one-step approach that could potentially have very wide implications.
"Currently, this technique would be especially useful for manufacturing better conducting membranes, microfluidics, and all-organic electronic devices," Strong said.
