| Outline of Final Research Achievements |
In this study, we focused on the preparation of silicon nanosheets (Si-NSs) having electrical conductivity and a self-standing thin film of Si-NSs. As a result, we revealed that the electrical conductivity of Si-NSs was controlled by the lithiation of Si-NSs which proceed by a mechanochemical solid phase reaction of Si-NSs and metallic lithium. In addition, we succeeded to prepare Si-NSs/polystyrene composite (Si-NSs/PS) by the reaction of Si-NSs with styrene. Si-NSs/PS dissolved in organic solvents and formed a self-standing thin film by drying of the Si-NSs/PS slurry on the flat plate.
