Facile synthesis of one dimensional graphene wrapped carbon nanotube composites by chemical vapour deposition

A unique method for synthesis of graphene wrapped carbon nanotubes was developed by chemical vapor deposition. Raman analyses show that defects have been created during growth which helps in the efficient dispersion of the composites in a variety of solvents. The synergistic combination of 2D graphene and 1D carbon nanotubes with high electrical conductivity (30 S m(-1)) can be exploited for energy and sensing applications.
