Technical information ***
Solid content (% in water)	1.3–1.7	1.3–1.7	1.1
Resistivity, $\rho$ (Ω·cm)	500–5000	500–5000	N/A
Resistance (Ω/sq) *	N/A	N/A	<100

* The unit was presented differently as Ω/sq (sheet resistance (R_sq)), where $\rho$ = R_sq·d (resistivity equals to sheet resistance times the layer thickness, and when the thickness d is 1, the resistivity equals to resistance). The PEDOT:PSS Orgacon ICP 1050 was classified as a highly conductive grade. ** All the data presented in the upper block was taken experimentally from our measurements. *** All the data presented in the lower block was taken from the technical information provided by each company.
