Over the last three decades, carbon (one of the most abundant materials found on earth) and carbon nanomaterials (carbon allotrope forms such as 0D fullerenes, 1D carbon nanotubes, and 2D graphene) have attracted significant attention due to their unique electronic, thermal, mechanical, and chemical properties. Recent advances in the synthesis and assembly techniques have renewed interest in employing carbon nanomaterials as the basis of electronic applications, and the flexibility and the low cost of these materials provide the opportunity for many applications such as wearable, disposable, and next-generation electronics. In addition, in these material systems, we can dramatically change their properties by engineering the surface, defect, phase, and interface.

In this talk, I will deliver the recent progress regarding the synthesis of carbon nanomaterials and provide related applications for functional nanocomposite materials and electronic devices. Especially, this talk mainly affords studies on the chemical functionalization of graphene and introduces how to modify the surface and interface of 2D vdW heterostructures and control the defects for a broad range of practical applications such as electronics, spintronics, bio-sensors, and energy harvesting.
