Carbonene materials are all-carbon materials composed of sp2 hybridized carbon atoms bonded in hexagonal rings, including graphene and carbon nanotubes. Due to their unique structure and superior properties, carbonene materials are strategic materials that can play a core role in future semiconductors, micro/nano-electronics, energy and lightweight materials with high strength. The structure-controlled synthesis and study of their fundamental properties are essential for the possible breakthroughs in frontier sciences and industrial applications. Our research focuses on the controlled synthesis and assembly of carbonene materials, the discovery of their novel physic-chemical properties and the exploration of frontier applications. Synthesis determines the future. We devote ourselves to developing the synthesis methodology, bridging between the micro- and macro- structures, revealing the transmission law of properties between nanomaterials and macro assemblies, and finally achieving demand-oriented customized synthesis of carbonene materials. Our research includes: (1) the growth methodology of carbonene materials; (2) the preparation and application of carbonene fiber; (3) the exploration of new carbon allotropes; (4) Raman spectroscopy of carbon nanomaterials.

Raman spectroscopy has been an important tool for the characterization of carbon nanomaterials. Based on the understanding of the physical picture of Raman scattering, we aim to develop new techniques of Raman spectroscopy for the characterization of low-dimensional materials, such as angle-resolved polarized Raman scattering, helicity-resolved Raman scattering and graphene-based enhanced Raman scattering. |
