Sulfophenylation of polysulfones for proton-conducting fuel cell membranes
(2002) In Macromolecular Rapid Communications 23(15). p.896-900- Abstract
- Polysulfone has been sulfophenylated by lithiation and anionic reaction with 2-sulfobenzoic acid cyclic anhydride. This provides a new convenient method to modify polysulfones by attaching pendant sulfonated phenyl groups via ketone links. Membranes of the sulfophenylated polysulfones show promise for use in proton-exchange-membrane fuel cells. For example, a membrane with 0.9 sulfophenyl units per repeating polysulfone unit and 30 wt.-% water was found to have a proton conductivity of 32 mS/cm at 60degreesC.
