Simultaneous improvement of power density and durability of sulfonated poly(ether ether ketone) membrane by embedding CeO2‐ATiO2: A comprehensive study in low humidity proton exchange membrane fuel cells

International Journal of Energy Research, 2022
Herein, we describe the incorporation of cerium oxide‐coated amine‐functionalized titania nanorods (CeO2‐ATiO2) as a bifunctional nanofiller in sulfonated poly(ether ether ketone) (SPEEK) as a cost‐effective and high‐performance proton exchange membrane (

Sulfonated poly(ether sulfone ether ketone ketone)/sulfonated poly(ether sulfone) blend membranes with reduced methanol permeability

High Performance Polymers, 2012
Proton exchange membranes were prepared by blending sulfonated poly(ether sulfone ether ketone ketone) (SPESEKK) with sulfonated poly(ether sulfone) (SPES). The morphology, tensile strength, proton conductivity and methanol permeability of the blend membranes were investigated.

Biofilm behavior on sulfonated poly(ether-ether-ketone) (sPEEK)

Materials Science and Engineering: C, 2017
Poly(ether-ether-ketone) (PEEK) has also shown to be very attractive for incorporating therapeutic compounds thanks to a sulfonation process which modifies the material structure resulting in a sulfonated-PEEK (sPEEK). Concerning biomedical applications, the objective of this work was to evaluate the influence of different sulfonation degree of sPEEK ...

Synthesis and structural properties of sulfonated poly ether ether ketone (SPEEK) and Poly ether ether ketone (PEEK)

AIP Conference Proceedings, 2020
Polyether ether ketone (PEEK) is one of the most important aromatic polymers; it has many applications in nanotechnology. The new sulfonated polyether ether ketone (sPEEK) membrane was successfully prepared, by using sulfonation processed for PEEK polymer; 10 grams of PEEK sample were dissolved progressively in 200 ml of sulfuric acid (H2SO4).

Cation permeable membranes from blends of sulfonated poly(ether ether ketone) and poly(ether sulfone)

Journal of Membrane Science, 2002
Sulfonated poly(aryl ether ether ketone), S-PEEK, is blended with non-sulfonated poly(ether sulfone) (PES) to adjust the properties of ion permeable and ion selective membranes. In this study, membranes are prepared from blends with (i) a S-PEEK content between 10 and 100 wt.% using one S-PEEK batch with a fixed degree of sulfonation and (ii) from ...
