We prepared and characterized flexible thermoelectric (TE) materials based on thin films of single-walled carbon nanotube (SWCNT) composites with polyvinylalcohol. While pristine SWCNTs incorporated in a polymer matrix generated a p-type TE material, chemical functionalization of SWCNTs by using polyethyleneimine produced an n-type TE material. TE modules made of both p- and n-type composite were...
The structure and the electrical, mechanical and optical properties of few-layer graphene (FLG) synthesized by chemical vapor deposition (CVD) on a Ni-coated substrate were studied. Atomic resolution transmission electron microscope (TEM) images show highly crystalline single-layer parts of the sample changing to multi-layer domains where crystal boundaries are connected by chemical bonds. This suggests...
Hydrogen adsorption in different carbonaceous materials with optimized structure was investigated at room temperature and 77K. Activated carbon, amorphous carbon nanotubes, SWCNTs and porous carbon samples all show the same adsorption properties. The fast kinetics and complete reversibility of the process indicate that the interaction between hydrogen molecules and the carbon nanostructure is due...
