摘要

The proton exchange membranes(PEMs) were prepared through the solution mixing method of sulfonated poly(ether ether ketone ketone)(sPEEKK) and cellulose.Cellulose was dissolved by 1-allyl-3-methylimidazolium chloride(AMIMCl) and then mixed with sPEEKK solution,sPEEKK/cellulose(SC) composite membranes were prepared by solution casting.The membranes have high flexibility and transparency,which meant the compounding in molecular level.Meanwhile,the composite membranes showed excellent mechanical properties and high proton conductivity.The mechanical property reached 29 MPa,and the proton conductivity was as high as 0.32 S/cm.Thus,as a kind of biomaterials,cellulose could be an excellent reinforcing material for poly(aryl ether ketone)(PAEK) based PEMs.
