Interlayer interaction and disorder in Few Layer Graphene (FLG) powders prepared by fluidized bed chemical vapor deposition

Bacsa R., Bacsa W.S., Serp Ph., Lecante P., Pavlenko E., Cameán I., Ramos A., Garcia A.B., Bacsa R., Bacsa W.S., University of Toulouse, FR

The growth of few layer graphene (FLG) in powder form by CVD is particularly promising for its large scale production and use in composites as well as electrochemical and energy applications. The electronic and mechanical [...]

Correlating electrical and structural properties in surface layer of carbon nanotube polymer composite

Pavlenko E., Tishkova V., Puech P., Bacsa W.S., CNRS and University of Toulouse, FR

We have recently shown that annealing of agglomerated carbon nanotubes on thermoplast polymers form surface composite films (70 micrometers) (1). This has been explained by preferential carbon nanotubes absorption of infrared radiation leading to local [...]

Unusual thermal diffusion of carbon nanotubes in a thermoplastic polymer

Tishkova V., Pavlenko E., Puechmont P., Flahaut E., Bacsa W.S., CEMES, Univ. Toulouse, FR

The dispersion of carbon nanotubes in polymer composites is a major challenge. Although nanotubes have a high aspect ratio, their tendency to agglomerate limit percolation at low loading. We find that thermal diffusion is reducing [...]
