All chemicals and reagents were commercially available, and we utilized these without additional purification. 1-ethyl-3-methylimidazolium bis(trifluoro-methylsulfonyl)imide (EMIM), polypyrrole (Ppy), dimethyl sulfoxide (DMSO), and phosphate buffered saline (PBS) were purchased from Sigma-Aldrich. The gas cylinders for NH3 (10 ppm), SO2 (76.3 ppm), and EtO (666 ppm) were purchased from RIGAS (Daejeon, Korea). Graphing and PCA analysis were achieved by using Origin software (OriginPro 2020, OriginLab Corp., Northampton, MA, USA)

Plasticware that were used for the entire experiments were beakers, volumetric flasks and measuring cylinders. All the plasticware were soaked in soapy water for 3 h and then washed and rinsed with deionized water. After rinsing with deionized water, plasticware were soaked in 5% HNO3 solution for efficient removal of any metals stuck on the walls, prior to oven drying at 35 °C for 12 h. The reagents that were used included, 100 mg/L multielement standard for metals (As, Al, Ba, Be, Ca, Cd, Co, Cr, Fe, Ga, K, Li, Mg, Mn, Na, Ni, Pb, Sb,Se, Sn Sr,Tb, Te, V and Zn), 70 % ACS grade nitric acid, 5 mL of 1-Ethyl-3-methylimidazolium bis (trifluromethylsulfonyl) and standard reference material for fuel oils (NIST1634c) and were all purchased from Sigma-Aldrich, South Africa. The real fuel oil samples (gasoline, diesel, and kerosene) were purchased from different fuel filling stations around Johannesburg, South Africa. The nylon microfilters (0.45 μm) were purchased from Anatech Instrument, South Africa.

PEO Mw = 5 × 106 g·mol−1 from Sigma-Aldrich (Sigma-Aldrich, St. Louis, MO, USA) was used to prepare the composites. LiTFSI, from Aldrich and neat sepiolite, kindly supplied by TOLSA S.A. (TOLSA, Madrid, Spain), were dried under a vacuum for 24 h. d -α-tocopherol polyethylene glycol 1000 succinate (TPGS), used to prepare the modified sepiolite TPGS–S, was purchased from Aldrich and used as received. Details on the preparation of TPGS-S have appeared elsewhere [14 (link)]. The RTILs employed to prepare the electrolytes listed in Table 1 were purchased from Solvionic (Solvionic, Toulouse, France), all of them with 99.5% purity. They are the following: 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide (EMIFSI), N-propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide (PMPFSI); N-propyl-N-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (PMPTFSI), 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide (EMITFSI).
Solutions of LiTFSI with RTILs and poly(ethylene glycol) methyl ether (PEG), Mn = 550 g·mol−1 from Sigma-Aldrich (Sigma-Aldrich, St. Louis, MO, USA) were prepared by magnetic stirring for 30–120 min, as model liquid phases for the solid polymer electrolytes.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
