Evaluation of the surface properties of poly(ionic liquid) materials by inverse gas chromatography was written by Wang, Qiang. And the article was included in European Polymer Journal in 2020.Recommanded Product: 915358-85-9 This article mentions the following:
Inverse gas chromatog. (IGC) was used as a tool to evaluate the surface parameters of three poly(1-alkyl-3-vinylimidazolium hexafluorophosphate) (P[CnVIM][PF6], n = 2, 4, 6) materials that were obtained by a free-radical polymerization IGC characterization was carried out at temperatures ranging between 303.15 and 343.15 K for determining the dispersive free energy (γds) as well as the Lewis acidity and basicity parameters of the three materials. The retention behavior of the probes on the surfaces of the three materials was analyzed by plotting the net retention volumes (Vn) of the probes as a function of temperature The dispersive free energy results revealed that all three materials have high γds values and that the γds value decreases in an almost linear fashion with increasing temperature The acid-base data for the three materials confirmed that the surfaces of all three materials can be considered to be amphoteric with a predominantly basic character and that the basicity decreases with increasing alkyl side chain length on the imidazolium backbone. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9Recommanded Product: 915358-85-9).
1-Butyl-3-vinyl-1H-imidazol-3-ium hexafluorophosphate(V) (cas: 915358-85-9) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.Recommanded Product: 915358-85-9
