Conductive polymeric composition and method for preparing the conductive polymeric composition

A viscous conductive polymeric composition comprising PEDOT and one or more ionic liquids made by a process comprising:

• (a) generating an aqueous suspension mixture comprising in % by weight:
• a PEDOT conductive polymer in an amount between about 0.2 and 10%,
• one or more ionic liquids in an amount between about 0.05-2.0%,
• a secondary dopant in an amount between about 0-50%,
• wherein the ratio (ionic liquid)/(PEDOT conductive polymer) is between about 0.5 and 15,
• by mixing and heating the PEDOT conductive polymer, the one or more ionic liquids, and the secondary dopant, thereby generating an aqueous suspension mixture, and
• (b) a first evaporating step comprising evaporating the water from the aqueous suspension mixture to generate a viscous aqueous suspension mixture comprising water in an amount between about 30% to about 99% by weight, wherein after the evaporating the aqueous suspension mixture has a viscosity of the mixture between about 100 and 10000 cP,
• wherein each of the one or more ionic fluids comprises a compound having a general formula (I)
• wherein
• R1 and R2 independently of each other are branched or cyclic linear alkyl groups, with chain C1-C15,
• X is an anion selected from alkylsulphates, tosylate, Ccarboxylates-i-Cs, such as formate and acetate, halides such as fluorides, chlorides, bromides and iodides, borates and phosphates, such as tetrafluoro borate and hexafluorophosphate, sulphonates.
