Description
Technical field
The invention belongs to sulfonated polyphenyl type proton transfer film material and synthetic method thereof.
Background technology
The polymkeric substance that contains the sulfonic group structure is as polymer dielectric, owing to it has unique proton conductivity and other high-performance is applied to fuel cell [L.Carrette, K.A.Friedrich, U.Stimming. fuel cell (Fuel Cells), calendar year 2001, the 1st phase, page 5] in.Present business-like proton transmission film has the nafion film of E.I.Du Pont Company and the Dow film of DOW company etc., but because the cost of these several films is expensive and high-temperature behavior instability [Q.F.Li, R.He, J.O.Jensen, N.J.Bjerrum.Chemical material (Chemistry Material),, the 15th phase, the 4896th page in 2003], promoted the broad research of other types proton transfer film materials.The sulfonated aromatic polymer is as SPSF [P.G.Dinitrova, B.Baradie, D.Foscallo, C.Poinsignon, J.Y.Sanchez.Membrane science magazine (Journal ofMembrane Science), 2001, the 185 phases, the 594th page], sulfonated poly (phenylene oxide) [K.Miyatake, Y.Chikashige, M.Watanabe.Macromole (Macromolecules), 2003, the 36th phase, the 9691st page], sulfonated polyether-ether-ketone [K.D.Kreuer, membrane science magazine (Journal of Membrane Science), calendar year 2001, the 185th phase, the 29th page] etc. be relatively more active several proton transmission films of research.But the sulfonation degree of the proton transmission film of this several types be difficult for to be determined, the bad mechanical strength of film, and protonated degree is low etc., and reason has limited their use.
Two kinds of methods of synthetic main employing of present proton transmission film: a kind of is directly polymkeric substance to be carried out sulfonation [K.Miyatake, Y.Chikashige, M.Watanabe with chlorsulfonic acid or oleum.Macromole (Macromolecules), 2003, the 36th phase, the 9691st page].The shortcoming of this method is that the position of sulfonation degree and sulfonation point is wayward, and the poor repeatability of film properties can cause the degraded of polymkeric substance in the sulfonation process, causes physical strength to reduce.Another kind method is by condensation reaction condense together [F.Wang, M.Hickner, Y.S.Kim, T.A.Zawodzinski, J.E.McGrath with the comonomer of sulfonation and unsulfonated.Membrane science magazine (Journal of Membrane Science), 2002, the 197th phase, the 2318th page].The proton transmission film of this method preparation, sulfonic group directly is connected on the main chain, and the close electric structure on the phenyl ring reduces sulfonic protonated degree, causes proton conductivity low.And when film absorbs water, can lose due physical strength because degree of swelling is too big.
The proton transfer film material of biphenyl type, because of it has scale resistance, hydrolytic resistance and high thermal resistance and cause investigator's attention [H.Ghassmi, J.E.Mcgrath.Polymkeric substance (Polymer),, the 45th phase, the 5847th page in 2004], but the preparation of the biphenyl type proton transfer film material in the document is to adopt oleum directly polymkeric substance to be carried out sulfonation, and sulfonation post polymerization thing can not film forming, can't be applied in the fuel cell.
