Abstract
The following article has been retracted at the request of the Journal Editor and Sage:
Yuan C, Wang Y. The preparation of novel sulfonated poly(aryl ether ketone sulfone)/TiO2 composite membranes with low methanol permeability for direct methanol fuel cells. High Performance Polymers. 2021;33(3):326-337. doi:10.1177/0954008320958044
The authors contacted the Journal Editor with a request to retract the article.
The authors explained that they used an incorrect image in Figure 7 to illustrate the sectional morphology of the polymer.
After an internal investigation Sage has become aware that the submission contains indicators of third-party involvement.
Due to concerns around author contributions to this article, as well as concerns around the integrity of the research process, Sage and the Journal Editor retract this article.
Author Y. W. agreed with the retraction but disagreed with the final notice. C. Y. did not respond to the decision to retract.
