Extended Data Fig. 10: CNT printing density.
From: Printable and recyclable carbon electronics using crystalline nanocellulose dielectrics
SEM images of CNT thin films printed on silicon using (a) pristine and (b) recycled CNT ink for purposes of determining printed density (45% and 36% coverage for new and recycled inks, respectively). c,d, For analysis, each image was set to binary using ImageJ, and in addition, in e,f, the color threshold was modified to help guide the eye. The decrease in printed ink density may help explain the slightly lower on-current with the recycled CNT ink.
