▎ 摘  要

Few layer graphene (FLG) was successfully coated with Sn/SnO after reacting with SnCl2 and reducing under H-2/N-2 gas. X ray diffraction and X ray photoelectron spectroscopy showed the formation of Sn/SnO on the surface. The thermal diffusivity and conductivity of similar to 1 mm thick pallet of Sn/SnO coated hybrid FLG was surged to 7.91 mm(2)/s, 14.41 W/m.K from 2.17 mm(2)/s and 3.27 W/m.K of the pristine FLG, respectively. The increase in thermal properties was attributed to the formation of compact structures in the film and reducing the air gaps by joining hybrid graphene due to Sn. Current-voltage measurements using tuna probe in atomic force microscopy demonstrated the higher number of negative charge carriers in the hybrid FLG compared to pristine FLG because of electron transfer from graphene to Sn. Study using transmission electron microscopy showed the development of interconnection using Sn/SnO hybrid graphene with Sn coated and filled multiwalled carbon nanotubes.
