AbstractThe effects of sulfonated polyether sulfone (s‐PSF) with different sulfonation degrees on the interfacial properties of carbon fiber (CF)/poly(ether‐ether‐ketone) (PEEK) composites were investigated systematically. The performance of the modified CF and the corresponding CF/PEEK composites and was tested and characterized.

Abstract In this study, a single layer graphene oxide is successfully synthesized and used as a nano-filler in a self-fabricated sulfonated polyether ether ketone (SPEEK) to make a composite proton exchange membrane, graphene oxide/SPEEK (GO-SPEEK). The properties of GO-SPEEK, Nafion® 117 and SPEEK are then compared to ascertain their selectivity to ...

Morphology Effect on Proton Dynamics in Nafion®117 and Sulfonated Polyether Ether Ketone
Journal of the Physical Society of Japan, 2016We report results of our experimental and theoretical studies on the dynamics of proton conductivity in Nafion® 117 and self-fabricated sulfonated polyether ether ketone (SPEEK) membranes. Knowing that the presence of water molecules in the diffusion process results in a lower energy barrier, we determined the diffusion barriers and corresponding ...

AbstractBACKGROUNDPolyether ether ketone (PEEK) was modified by a sulfuric and nitric acid mixed system to improve the solubility of the material and the gas selective permeability of the film. SN1 and SN5, synthesized from mixed acid systems (with ratios of nitric acid and sulfuric acid of 1:1 and 1:5, respectively) were chosen because they had ...
