标 题 :Development of novel proton-conductive polymers for proton exchange membrane fuel cell (PEMFC) technology
发明人：BAE CHULSUNG
权利人:REGENTS UNIVERSITY AND COMMUNI
摘要:New thermally and chemically stable sulfonic acid-containing polymers are synthesized via post-sulfonation of aromatic polymers. These new polymers provide unique benefits to proton exchange membrane fuel cell technology (“PEMFCâ€?). As a sulfonic acid moiety can be easily installed into an aromatic ring via electrophilic sulfonation, even in the presence of an electron-withdrawing substituent such as —F, rigid polymers consisting of aromatic rings at either the side chain or main chain can be prepared with a wide range of substituents and flexibility in properties. Novel synthetic procedures are provided for synthesis of the polymers.

摘要:A new series of wholly aromatic poly(arylene ether ether ketone ketone)s containing pendant sulfonic acid groups (SPAEEKK) were conveniently prepared by potassium carbonate mediated nucleophilic polycondensation reactions of inexpensive commercially available monomers: 1,3-bis(4-fluorobenzoyl)benzene (BFBB), sodium 6,7-dihydroxy-2-naphthalenesulfonate (DHNS), and 4,4′-biphenol or hydroquinone in N-methyl-2-pyrrolidone (NMP) at 170° C. FT-IR and NMR were used to characterize the structures and the sulfonate or sulfonic acid contents (SC) of the polymers. Flexible membrane films were obtained by casting N,N-dimethylacetamide (DMAc) solutions of copolymers. Membrane films in acid form were then obtained by treating the sodium form membrane films in 2 N sulfuric acid at room temperature. Glass transition temperatures (T g s) and decomposition temperatures (T d s) of SPAEEKKs in both sodium and acid forms were determined. Water uptake and swelling ratio values increased with SCs and temperatures. The proton conductivities of acid form membrane films increased with SC value and temperature and reached 5.6×10 −2 S/cm at 100° C. for SPAEEKK-100.

摘要:Polymers and copolymers containing 1H-benzo[d]imidazol-2(3H)-one units have been synthesized under conditions generally used for the synthesis of poly(aryl ether)s. 1H- n nbenzo[d]imidazol-2(3H)-one behaves like a biphenol in the polymerization reaction.n n The soluble homopolymer has a very high glass transition temperature (348° C.), good thermal stability, and forms flexible transparent films. Because of the low molecular weight (134.14) of the benzoimidazolone monomer in the copolymer formed with 4,4′-biphenol that contains 30 mole % of the benzimidazolone unit, only 8.9 weight % is required to raise the Tg of the poly(arlyl ether)sulfone from 220° C. to 269° C.
