Inorganic Chemicals
Studies from Jilin University in the area of inorganic chemicals described
January 14th, 2011
According to a study from Changchun, People's Republic of China, "Poly(ether ether ketone) (PEEK) and sulfonated poly(ether ether ketone) (SPEEK, IEC = 2.07 mequiv.g(-1)) have been synthesized via nucleophilic aromatic substitution reaction. Bromomethylated poly(ether ether ketone) (PEEK-Br) is then prepared and reacted with 2-benzimidazolethiol to obtain the benzimidazole grafted poly(ether ether ketone) (PEEK-BI)." "The structures of PEEK-Br and PEEK-BI are characterized by H-1 NMR spectra. Composite membranes based on SPEEK and PEEK-BI are prepared and their properties used for fuel cells are studied in detail. The results show that the composite membranes exhibit...
