An interdisciplinary research team of the Research Training Group (RTG) 2154 "Materials for Brain" at Kiel University (CAU) has developed a method to produce graphene-enhanced hydrogels with an excellent level of electrical conductivity. What makes this method special is that the mechanical properties of the hydrogels are largely retained. The material is said to have potential for medical functional implants, for example, and other medical applications.
"Graphene has outstanding electrical and mechanical properties and is also very light," says Dr. Fabian SchÃ¼tt, junior group leader in the Research Training Group, thus emphasizing the advantages of the ultra-thin material, which consists of only one layer of carbon atoms. What makes this new method different is the amount of graphene used. "We are using significantly less graphene than previous studies, and as a result, the key properties of the hydrogel are retained," says SchÃ¼tt about the current study, which he initiated.
