Mechanical properties of hybrid proton conducting polymer blends based on sulfonated polyetheretherketones

The mechanical properties of polymer blends made from sulfonated polyetheretherketone and sulfonated and/or silylated polyphenylsulfone (PPSU) are reported. Elastical modulus and maximum strength of membranes increase strongly by addition of silylated PPSU, whereas sulfonated PPSU softens the materi...

More Information
Summary:The mechanical properties of polymer blends made from sulfonated polyetheretherketone and sulfonated and/or silylated polyphenylsulfone (PPSU) are reported. Elastical modulus and maximum strength of membranes increase strongly by addition of silylated PPSU, whereas sulfonated PPSU softens the materials. A correlation is established between the water uptake coefficient measured after immersion in water and the elastic modulus of the membranes. The relation with membrane swelling during fuel cell operation is discussed.
