| Outline of Final Research Achievements |
We carried out ATR and quantum chemical calculation study of electronic spectra of graphene in FUV-DUV region. The absorption of graphene appears in the DUV region, however, we observed a new peak in the FUV region. Based on the results of TD-DFT and ZINDO calculations, it was possible to reproduce the spectral variations. These studies provide insights on the origins of the spectral variability of graphene as well as the molecular orbitals involved in FUV transition of graphene.
We also performed an ATR-FUV-DUV study of PHB and its nanocomposite with graphene. The major absorption of polymer occurs in FUV. The structural changes upon formation of the nanocomposite and heating cause spectral variations. The FUV absorption of the relaxed structures was determined to be significantly stronger than that of the crystalline state. These results are consistent with the observed temperature-dependent spectra of the pure PHB.
