In 2022,Shirase, Yuto; Matsumoto, Akinobu; Lim, Kean Long; Tryk, Donald A.; Miyatake, Kenji; Inukai, Junji published an article in ACS Omega. The title of the article was 《Properties and Morphologies of Anion-Exchange Membranes with Different Lengths of Fluorinated Hydrophobic Chains》.Recommanded Product: 1-Chloro-3-iodobenzene The author mentioned the following in the article:
An anion-exchange electrolyte membrane, QPAF(C6)-4, polymerized with hydrophobic 1,4′-bis(3-chlorophenyl)perfluorohexane and hydrophilic 6,6′-(2,7-dichloro-9H-fluorene-9.9-diyl)bis(N,N-dimethylhexan-1-amine) is phys. flexible and chem. stable. The drawbacks are relatively large water swelling and lower OH- conductivity at higher water uptakes, which are considered to be due to the entanglement of the flexible hydrophobic structure of the membrane. In this study, a QPAF(C4)-4 membrane was newly synthesized with shortened hydrophobic fluoroalkyl chains. Unexpectedly, QPAF(C4)-4 showed a higher water uptake and a lower bulk/surface conductivity than QPAF(C6)-4 possibly due to the decrease in hydrophobicity with a smaller number of fluorine atoms. The thermal stability of QPAF(C4)-4 was higher than that of QAPF(C6)-4, possibly due to the rigidity of the QAPF(C4)-4 structure. A higher mech. strength of QAPF(C6)-4 than that of QPAF(C4)-4 could be explained by the larger interactions between mols., as shown in the UV-visible spectrum. The interactions of mols. were understood in more detail with d. functional theory calculations Both the chem. structures of the polymers and the arrangements of the polymers in the membranes were found to influence the membrane properties. In the experiment, the researchers used many compounds, for example, 1-Chloro-3-iodobenzene(cas: 625-99-0Recommanded Product: 1-Chloro-3-iodobenzene)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. Organic iodides are used in veterinary products (Organic Iodide Powder) as a nutritional source of iodine. In the chemical industry, alkyl iodides serve as excellent alkylating agents and, specifically, methyl iodide is used as a methylating agent in the synthesis of various pharmaceutical drugs.Recommanded Product: 1-Chloro-3-iodobenzene
