Abstract
The micro-patterns of electrically conducting polypyrrole (PPy) with line width as low as 30 μm have been successfully achieved using a photolithographic method. PPy as a conducting pattern was chemically polymerized within the poly (vinyl alcohol) (PVA) matrix layer where ferric p-toluenesulfonate as an oxidant was embedded in a designed architecture. Surface resistivity and transmittance at 600 nm of PPy regions were in the range of 103 ∼ 105 Ω/□ and 50% ∼ 90%, respectively. The resistances of PPy patterns were in the range of 10 4 ∼ 106 Ω, which is lower than that of PVA region by about 1010 times.
