Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In order to enhance the thermo-chemical and mechanical proton exchange membrane (PEM) properties, a series of five blend membranes made from poly(vinylidene fluoride-co-chlorotrifluoroethylene) (poly(VDF-co-CTFE)) with a fluorinated copolymer containing phosphonic acid was synthesised. The mechanical properties of these blend membranes were assessed by dynamic mechanical analysis (DMA). In order to determine the influence of the fluorinated copolymer on the blend membrane morphology, a SAXS study was performed. The presence of the fluorine atoms in poly(VDF-co-CTFE) allows us to obtain membranes with a better structuration, but also to enhance the oxidative stability in the presence of radicals. The best result obtained shows a proton conductivity of 40 mS cm at 80 °C under fully hydrated conditions.
