3 4 ethylenedioxythiophene edot

Octadecane (99.9%), hexadecane (99%), iron(III) p-toluenesulfonate hexahydrate (99.9%), hydrogen peroxide solution (30 wt.% in H₂O), and poly(diallyldimethylammonium chloride) solutions (average M_w < 100,000, 35 wt.% in H₂O; average M_w = 200,000–350,000, 20 wt.% in H₂O; and average M_w = 400,000–500,000, 20 wt.% in H₂O) were purchased from Sigma-Aldrich/Merck (Darmstadt, Germany); 3,4-ethylenedioxythiophene (EDOT, 99%) was acquired from Alfa Aesar (Karlsruhe, Germany). All chemicals were used as received without further purification. Ultrapure MilliQ water was used for all the experiments.

Poly(diallyldimethylammonium chloride) (PDADMAC) with a molecular weight of 10⁵ g mol⁻¹, sodium deoxycholate (DOC), 1-Butyl-3-methylimidazolium hexafluorophosphate (PF₆), and 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BTFMSI) were purchased from Sigma-Aldrich (Madrid, Spain). 3,4-Ethylenedioxythiophene (EDOT), lithium perchlorate, and acetonitrile were purchased from Alfa Aesar (Barcelona, Spain). Multiple-wall carbon nanotubes (MWCNTs) were obtained from Bayer Material Science (Leverkusen, Germany, 12–15 nm outer and 4 nm inner wall diameter, length > 1 mm, purity 95 wt%). Nonwoven felt fabric (made of polyester fibers) with a grammage of 140 g m⁻² and 0.8 mm thickness was purchased from MW Materials World (Barcelona, Spain). All chemicals were used as received.
