Users at BESSY II: Nafion, the talented membrane for fuel cells and 4D-printing
Thermoplastic ionomer materials such as Nafion do have many talents: they can be used as membranes for proton exchange in fuel cells, but they have also attracted attention as shape memory materials: Via external stimuli such as heat or an electric field, it is possible to trigger a change in shapes. Applications in textiles, biomedicine, aerospace, sensors and coatings are possible. Nafion: a membrane with shape memory Nafion is one of those materials: as a membrane in a fuel cell, its high proton conductivity allows a fast pass of hydrogen ions (protons). And its internal shape plays a crucial role. Now a team from Brazil hasRead More →
