1 ethyl 3 methylimidazolium bis trifluoromethylsulfonyl imide emim tfsi

Processing solvents such as acetone, chloroform, and 2-propanol were purchased from Sigma-Aldrich. Regioregular P3HT (M_n: 54,000–75,000, lot number: MKCK1947), PVdF-HFP (M_n: 110,000), and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM:TFSI) ionic liquid were also purchased from Sigma-Aldrich. The azide crosslinker bis(6-((4-azido-2,3,5,6-tetrafluorobenzoyl)oxy) hexyl)decanedioate was synthesized as previously reported^{42 (link)}. P3HT solution was prepared by dissolving P3HT in concentrations of 3, 5, 7, 9, 11, and 13 mg mL⁻¹ in chloroform for obtaining P3HT organic channels of various thicknesses. After being stirred on a hot plate for 5 h at 50 °C, the P3HT solution was blended with the azide crosslinker (5 mg mL⁻¹ in chloroform) in a 4:1 ratio. Ion-gel solution was prepared by mixing the EMIM:TFSI ionic liquid, PVdF-HFP, and acetone solvent in a 4:1:7 ratio. The ion-gel solution was stirred at 50 °C for 5 h before use.
