Multi-functional 2D hybrid aerogels for gas absorption applications
Charalampos Androulidakis, Maria Kotsidi, George Gorgolis +5
Aerogels have attracted significant attention recently due to their ultra-light weight porous structure, mechanical robustness, high electrical conductivity, facile scalability and…
Tunable macroscale structural superlubricity in two-layer graphene via strain engineering
Charalampos Androulidakis, Emmanuel N. Koukaras, George Paterakis +2
Achieving structural superlubricity in graphitic samples of macro-scale size is particularly challenging due to difficulties in sliding large contact areas of commensurate stacking…
Stress-transfer from polymer substrates to monolayer and few-layer graphenes
Ch. Androulidakis, D. Sourlantzis, E. N. Koukaras +2
In the present study the stress transfer mechanism in graphene-polymer systems under tension is examined experimentally using the technique of laser Raman microscopy. We discuss in…
Compression behavior of simply-supported and fully embedded monolayer graphene: theory and experiment
Emmanuel N. Koukaras, Charalampos Androulidakis, George Anagnostopoulos +2
Single layer graphene simply-supported on a polymer substrate was subjected to axial compression and its behavior upon loading was monitored with laser Raman spectroscopy (LRS). Th…
Wrinkled few-layer graphene as highly efficient load bearer
Charalampos Androulidakis, Emmanuel N. Koukaras, Jaroslava Rahova +5
Multilayered graphitic materials are not suitable as load-bearers due to their inherent weak interlayer bonding (for example, graphite is a solid lubricant in certain applications)…
Stress Transfer Mechanisms at the Submicron Level for Graphene/Polymer Systems
George Anagnostopoulos, Charalampos Androulidakis, Emmanuel N. Koukaras +5
The stress transfer mechanism from a polymer substrate to a nano-inclusion, such as a graphene flake, is of extreme interest for the production of effective nanocomposites. Previou…
Graphenes flakes under controlled biaxial deformation
Charalampos Androulidakis, Emmanuel N. Koukaras, John Parthenios +3
Thin membranes, such as monolayer graphene of monoatomic thickness, are bound to exhibit lateral buckling under uniaxial tensile loading that impairs its mechanical behaviour. In t…
Experimentally derived axial stress- strain relations for two-dimensional materials such as monolayer graphene
Ch. Androulidakis, G. Tsoukleri, N. Koutroumanis +5
A methodology is presented here for deriving true experimental axial stress-strain curves in both tension and compression for monolayer graphene through the shift of the 2D Raman p…
Failure Processes in Embedded Monolayer Graphene under Axial Compression
Charalampos Androulidakis, Emmanuel N. Koukaras, Otakar Frank +7
Exfoliated monolayer graphene flakes were embedded in a polymer matrix and loaded under axial compression. By monitoring the shifts of the 2D Raman phonons of rectangular flakes of…
