Fig. 2. Comparison between oCVD PEDOT and PEDOT:PSS.
(A) Photo images of fabrics (nylon, polyester, and cotton) coated by oCVD PEDOT and PEDOT:PSS. The insets demonstrate a droplet of PEDOT:PSS solution on each fabric, representing the fabric’s hydrophobicity. (B) Uniformity tests: fabricating multiple electrode pairs on PEDOT-coated polyesters using silver paste with a channel width of 6 mm and different channel lengths from 6 to 30 mm. (C) SEM images of oCVD PEDOT and PEDOT:PSS on polyester before and after bending 100 cycles. (D) Resistance change during the bending tests. Photo credit: Hyeonghun Kim, Purdue University.
